Hundreds of anti-war rabble-rousers blast 'insane' and 'evil' David Cameron for launching air strikes in Syria as they march through London

Hundreds of anti-war protesters blasted David Cameron for launching air strikes in Syria at a march through London today.

The Stop the War rally gathered outside BBC Broadcasting House in central London before marching to Downing Street, with the Prime Minister labelled as 'insane' and 'evil' by one activist.

They also took aim at the 66 Labour MP's who voted for the military action against ISIS terrorists, going against party leader Jeremy Corbyn's stance.

Prime Minister David Cameron came under fire from protesters and was branded 'insane' and 'evil'

It comes hours after former Stop the War chairman Mr Corbyn attended a fundraising dinner for the organisation despite some Labour MP's urging him to avoid it. 

The Socialist Party supplied an open microphone for the event, with over a dozen speakers lining up to voice their anger under the watchful eyes of police.

One speaker, who gave his name as Tony, said Mr Cameron was 'insane' and 'evil' for pursuing a more aggressive approach.

He added: 'You can't bomb your way to peace.'

Helen Pattinson, 24, who is part of a group that has been campaigning at schools, questioned the funding for military action.

But critics of Stop the War have said it is more 'anti-West' than anti-war

She said: 'How come they can find money to drop bombs on other countries to create refugees... but they can't find money for health, for education, and for young people to have a decent future?'

Nancy Taaffe, from the Socialist Party, told the crowd: 'We've been here before people, haven't we?

'When we're told about peace and reconstruction, and then... we see the bodies coming back, we see the bombs in Baghdad market and the sectarian civil war erupted when they kicked the hornets' nest of the Iraq war.'

She added: 'We say no to the continued violence, we say no to the terror and we say no to the racism that is the fallout of this war.' 

The protest closed streets as it weaved along Regent Street, past Piccadilly Circus and Trafalgar Square. The crowd chanted: 'Stop bombing Syria, no more war" and "They say warfare, we say welfare'.

In a speech issued in advance of last night's fundraiser, Mr Corbyn said that Stop The War ‘has brought hundreds of thousands of people on to the streets time and again' and 'has organised protests and lobbies in every part of the country, including by military families’.

'Most of all, it has been shown to be right in opposing more than a decade of disastrous wars – in Afghanistan, Iraq and Libya – while many of its critics supported them,' he added. 

But critics of the movement say members have abused and tried to intimidate Labour MPs who voted in favour of bombing Syria.

Labour MP and former frontbencher Emma Reynolds added that Stop The War was ‘more anti-West than anti-war’.

Some 500 Labour supporters signed a letter urging Mr Corbyn to cancel his appearance before the far-Left group, which they said blamed liberal western democracies for everything and were ‘all-but absolving dictators and terrorists of their butchery'.
