Meanwhile, back in December Michelle paid an emotional tribute to her fiancé and sang his favourite song at his funeral a day before what would have been his 35th birthday.

During the funeral, Dockery stood at the altar and told the congregation: 'Whether in his work or his personal life John was extremely loyal. It was clear that when John was in your corner he was there. 

'I was honoured to know John. To love him and be loved by him. He was my friend, my King, my hero, my everything. We celebrate him, we honour him and we will miss him.'
