We can see Granny's house from here! Prince Harry jokes about spotting Buckingham Palace as he takes a spin on The London Eye with Kate and William to mark World Mental Health Day

  • Kate, 34, looked surprisingly summery in floaty rose print dress
  • She was joined by Prince William and Prince Harry for World Mental Health Day engagements 
  • Royal trio are representing their charity campaign Heads Together
  • Will meet with people who have battled psychological problems to hear about help they received
  • Royals will take to The London Eye with people who have shared their experiences

He wouldn't be the first tourist to look out for a famous landmark on The London Eye, so it's no surprise that Prince Harry couldn't resist trying to spot Buckingham Palace from a pod on the iconic landmark this afternoon.

Harry, together with William and sister-in-law Kate took a ride on the London Eye with young people who have battled psychological problems and been brave enough to share their experiences at a reception at County Hall for World Mental Health Day. 

The Duchess of Cambridge also gave a rare address, taking to the microphone to pledge that they will do 'what they can to shine a spotlight on emotional wellbeing'.

She also hinted at her husband and Harry's grief at losing their mother as she said, 'all of us know someone who has been through emotional times.' 

Later Harry chatted to Theresa Cox, 48, a carer for husband Andy Cox, 52, who has the debilitating condition Multiple System Atrophy – a rare neurological condition that has seen him go from being an active person to finding it difficult to climb the stairs.

Mrs Cox from Hughenden Valley, Bucks, who is a support worker in a secondary school, said: 'Harry was very down to earth, he told us to look out for his grandmother’s building and wave. He couldn’t remember if she was home or not so we were looking to see if we could spot her royal standard.'

She added: 'I think the stigma of mental health needs to go. It’s a really dark place and one that isn’t always seen, and I think some people don’t even understand they’re dealing with their own emotional health – almost until it’s too late.'

They royals spent around 30 minutes in a pod enjoying spectacular views of the capital which increased as they travelled upwards, giving them a bird’s eye view of London landmarks like Buckingham Palace – which flies the royal standard if the Queen is in residence - St Paul’s Cathedral and the City’s skyscrapers.

There were a number of couples, either friends, relatives or colleagues, who joined the royals in the pod, and they told their royal hosts how one person had been helped by the other, when they had suffered from depression or other psychological problems.

Before they left the couple met with a group of children from Abacus Nursery in Streatham Hill, south london, who had been walking by after a visit to the nearby London Aquarium.

They bent down and chatted wth the excited youngsters, Harry telling them he couldn't believe that they had seen crocodiles at the attraction.

Asked if they had 'seen the princess', one little boy replied: 'Well, I saw the Kate one.'

They were eager to tell Prince Harry how they had seen crocodiles and when asked if they had met a Princess, one boy replied: 'I met the Kate one'.  

Earlier today, The Duchess of Cambridge glowed in pretty pink floral dress as she arrived on London's Southbank. 

Kate, 34, on her first public engagement since returning from an official tour to Canada a week ago, sported the £428 summery knee-length Kate Spade New York dress - without a coat, despite the bright but biting autumn sunshine - as the royal trio attended an event at London's County Hall to an event to publicise the issue of good mental health.

Keep it chic in a pussy bow dress by Kate Spade

With the Royal tour of Canada at an end we weren't sure when we'd get to do a bit of fashion spotting on the Duchess of Cambridge again, but lo and behold she's out and about today and it's like she's never been away.

In Canada Kate tried some new labels like See by Chloé and Preen by Thornton Bregazzi and it seems like she's sticking to the trend by wearing a dress by Kate Spade. This stateside label is a favorite of her sister Pippa Middleton and Kim Murray who both have a similar aesthetic to the Duchess, so we're just surprised she hasn't worn it before.

In a pretty shade of pink with a dusky rose print it's ultra feminine as you'd expect, a feel that is only accentuated by the retro pussy bow neck tie and the pleated skirt. The good news for all you Kate obsessives out there is it's available to buy so click (right) to snap it up at Nordstrom before the Kate effect takes hold.

Then wear with a pair of classic blush courts to complete the look. Or you can, of course, shop our edit of similar blooming lovely frocks below.

Outside the Eye the royals were greeted by Rosi Prescott, Deputy Lord Lieutenant for Lambeth, and David Sharpe, Divisional Director of London Midway attractions, which runs the London Eye.

Kate was given a posy from Joanne Sibly, 17, who has been chosen to represent Merlin's Magic Wand, the charity which grants wishes to children who are sick, bereaved or terminally ill. They were also greeted by Ian Cheshire, Chairman of Heads Together and Elisha London, Head's Together's Campaign Director.

William, Kate and Harry will spend the day talking to those who have battled with psychological problems - and hear about the help they have received, in keeping with the theme of this year's awareness day, which is 'mental health first aid'.

At County Hall, they attended a reception where they met young people whose lives were changed thanks to crucial support from a relative, colleague or friend.

In the Riverside room in County Hall the royals mingled with people who have been helped by the eight mental health charities brought together by Heads Together. 

They spoke to people who have struggled with mental health issues or who have overcome a difficult time in their lives alongside the friends of family members who have supported them. 

Kate spent several minutes talking to Richard McGhee and his mum Sharon about mental health in the emergency services and revealed that she often listens to her husband talk about what he has seen during his shifts as an air ambulance pilot. 

THE LONDON EYE & LIGHT UP PURPLE CAMPAIGN

Later today, the London Eye will light up in purple in support of World Mental Health Day, joining other buildings around the world that will be doing the same. 

This will connecting Heads Together with the worldwide movement to end stigma around mental health.

Other London landmarks that will be lit include, The National Theatre, The Tower Of London, Madame Tussaud's and the Trafalgar fountains are lighting up purple tonight.

The global Light Up Purple drive was set up in memory of Canadian teenager Amanda Todd, who killed herself in 2012.

The 15-year-old brought the problem of cyber bullying to mainstream attention after she posted a video on YouTube in which she told her story with handwritten signs. 

Meanwhile celebrities including James Corden took to Twitter to share photographs showing circles drawn on their palms. 

Stars including Ed Sheeran, Dermot O'Leary and Rizzle Kicks all posted pictures to support the NHS and YMCA mental health campaign highlighting the worrying statistic that more than half of young people who experience stigma due to mental health problems say their own friends are the ones who bully them.

He said afterwards: 'My story is depression and anxiety. 'I work in the fire service so there's a certain aspect of that that can trigger it. 

'It's good to speak to people like the Duchess, not because she's royalty but just because it can highlight mental health more. 

'I was talking about my experiences and she also related to William in the air ambulance and how things might be quite similar. 

'Obviously she hears stories from him when he goes home and she was saying how she thinks that there's not a very good system...to highlight mental health and what people might go through.'

He added: 'She said she talks to him when he comes home.'

Morgan Noquet, 19, from Brighton told the royals how she was inspired to train to become a midwife after her own midwife Mitch Denny helped her through her mental health problems in pregnancy.

Morgan said: "They wanted to know about our story and we spoke about mental health in general and how they can help break down the stigma and get everyone talking about it and make improvements.

"With their status and their profile the fact they've chosen mental health, especially as it's got so much stigma, to hear people who everyone know talking about that is so helpful."

Mitch added: 'Kate spoke about being a mum and we talked about how her life is high profile and different from Morgan's life day to day. But you [Morgan] were saying sometimes it's difficult with Luna your daughter and she was agreeing with that.'

Morgan, who is mum to Luna, 20, months added: 'It's quite nice knowing that they are also parents and normal in that respect.

I was saying when my mental health is good it has an impact on my daughter and she's calm and collected, but at the same time she is a toddler and she can be a bit wild. They were just agreeing with it.

Mitch added: 'They said "I think we've got one of those".'

WILLIAM, KATE AND HARRY'S SPEECHES ON WORLD MENTAL HEALTH DAY 

William: Mental health is not a dirty word

 'Thank you so much for joining the Heads Together campaign on World Mental Health Day. Catherine, Harry and I are incredibly proud to be working with you all to tackle one of the greatest challenges facing our society.

'Mental health is not a dirty word – we all have mental health like we do physical health, good or ill. But not seeking help at those times when it all seems too much, or we are depressed or anxious, can impact the rest of our lives. Put simply, the three of us want to make asking for help no longer a big deal.

'On the Heads Together journey so far we have seen the difference that a listening ear can make to people’s lives – whether a father supporting a child suffering depression, a soldier who has returned from a testing deployment, or a child struggling with the pressures of a new school.

'Personally, in my work at the Air Ambulance, I see how colleagues and families help each other through traumatic moments.

'The three of us have learnt a lot in the past few months as we have met people. The conclusion we are coming to, is that the more we all talk about this, the more collectively as a society we can do to support one another.

'The theme of World Mental Health Day this year matches this. It is 'mental health first aid for all'.

'To us, mental health first aid means getting in there early to support people, before what they're going through becomes more serious or even clinical.

'That support can be as little as a conversation and a listening ear – or it can be signposting someone to a professional service. These actions may seem little, but they are vitally important.' 

Kate: 'We know how hard it can be to see a way forward.' 

'We are fortunate to be meeting and celebrating today with inspiring people who have been there for friends, colleagues and family at crucial times in their lives.

'All of us know someone who has been through difficult emotional times, and we know how hard it can be to see a way forward.

'William, Harry and I feel it is our duty to do what we can, with your help, to shine a spotlight on emotional wellbeing and highlight the support that is out there to prevent or manage the pain at difficult times.

'The three of us are coming to the realisation that more needs to be done to support people who are seeking help. Over the coming months, we hope to explore what else we can do to increase the level of service and support that people can receive.

'But first, as William said, we must tackle the stigma that stops people asking for help in the first place. We want to encourage people to talk to one another.

There are many people who are here today in order to share their own, very personal experience of the kind of support that can make the difference between coping and not coping – between good mental health and poor mental health.'

Harry: 'It's time we ended the shame around mental health.'

'William, Catherine and I want everyone to know how to give exactly the vital mental health support that you have talked about.

'It's not rocket science, but most of us don't know what to do if a friend or family member is suffering. Having some basic knowledge, and having the confidence to act on your knowledge, can make a huge difference to those around us – as Rich was for Dan.

'As William said earlier, we all have mental health just as we all have physical health. Too often we think mental health problems are things that happen to other people, not us.

'But we will all experience pressure on our mental health at some point during our lives. The more we accept that, the better we can help each other. Catching it and recognising it early, saves lives.

'So, it's time we ended the shame around mental health – the fear of judgment that stops people talking or getting help.

'One of the upcoming opportunities we have to spread the message about ending the stigma on mental health is the Virgin Money 2017 London Marathon – one of the largest sporting and mass participation events on earth.

'Heads Together has the privilege of being the 2017 charity partner of the year. We want as many London Marathon runners as possible, spectators around the course and people watching at home to get involved and make it a marathon for mental health.

'All of us have mental health. So the more we all get behind this topic, the more we can help not just the individuals suffering, but also their entire families and work colleagues as well. Together we will break the stigma forever and save lives.

'So, thank you for supporting Heads Together. It is a campaign with huge ambition for 2017 and the years ahead that can only be achieved with the support of all of you.

'The challenge is great but when we put our Heads Together we can achieve great things. Thank you.'   

The three royals then gave a joint speech in which they spoke about the issues around mental health.

William spoke first and called for mental health not to be treated like a 'dirty word'.

He said: ' Mental health is not a dirty word – we all have mental health like we do physical health, good or ill. But not seeking help at those times when it all seems too much, or we are depressed or anxious, can impact the rest of our lives. Put simply, the three of us want to make asking for help no longer a big deal. '
