Jeremy Corbyn’s policies must be carried through, warns FBU chief Matt Wrack

Stephen Doughty, a member of Hilary Benn’s shadow foreign affairs team, also urged Mr Corbyn not to attend the event.

That might involve a reshuffle, but after Labour’s success in the Oldham West and Royton byelection and Corbyn’s success in winning majority support for his position on airstrikes, even on a free vote, he wants to concentrate on ensuring that shadow ministers such as Hilary Benn reflect the leader’s thinking.

Caerphilly County Borough’s two other MPs, Islwyn’s Chris Evans and Merthyr Tydfil and Rhymney’s Gerald Jones, voted against the UK Government motion.

The Metropolitan Police has launched an investigation.

She was threatened after voting to bomb Islamic State terrorists in Syria.

In response, Mr McDonnell said the party leadership is not behind the intimidation of MPs who disagree with Mr Corbyn.

And he called on Mr Corbyn to distance himself from the Stop the War Coalition, one of the leading opponents of military action in Syria, accusing them of making a series of “ugly comments”.

They picketed Labour party headquarters when we were trying to run a phone bank for the Oldham by-election.

“They are a really disreputable organisation”.

Mr Corbyn stepped down as chairman of the organisation after he became Labour leader and did not attend a march in London organised by the group on the eve of Wednesday’s vote.

Earlier, Matt Wrack, general secretary of the Fire Brigades Union (FBU), said Mr Corbyn’s election “reflected as mood among a large number of people in the Labour movement” that “wanted to see a change in direction of politics”.

But Stop the War has triggered outrage by comparing the terrorists of ISIS to the freedom fighters who fought against Fascism in Spain in the 1930s.

But Lindsey German, Stop the War’s convenor, hit back, saying that Stop the War had not condoned any bullying or threats, adding that the protest at Labour HQ need not have led to the cancellation of any work inside the building.

The group says MPs, as public figures, should expect lobbying on issues of war and peace and it does not condone any online abuse.

She told BBC Radio 5’s Pienaar’s Politics that the Shadow Cabinet should continue to represent “every different strand of opinion” held by Labour MPs.

The party he said was “far more unified and united than it is sometimes presented as in the media”. They whipped their acquiescent MPs into line.

Some close to Mr Corbyn had anxious about the Christmas fundraiser becoming a distraction for the leader but Mr Hunt’s intervention appeared to harden his determination to go.

Mr Bryant said it was “up to Jeremy to decide who is on his frontbench, and I’m not going to tell him who should or shouldn’t be there”, but insisted Labour was a broad church today.

Mr Hunt, who decided not to serve under Mr Corbyn, said talk of a “purge” of opponents seemed a bit of a “Sunday story”.

He pointed to its outspoken attack on shadow foreign secretary Hilary Benn following his Commons speech backing air strikes on Syria as well as its response to the attacks in Paris.

He added: “I think it is going to develop into a positive alternative for the country”.
