George Osborne is to address German business leaders on Tuesday - this evening he set out some more detail on the UK's EU referendum renegotiation demands. Also tonight, a Labour minister said her party would consult the Stop the War Coalition on any vote on military action in Syria. Expect more on this on Tuesday, with the Foreign Affairs Select Committee due to give its verdict. Earlier, senior civil servants denied the collapsed Kids Company charity was given "special treatment", David Cameron defended proposed new web surveillance powers and the date for the Oldham West and Royton by-election was confirmed.

Labour would consult the Stop the War coalition about any proposal to bomb Syria, a shadow foreign minister has revealed.

The announcement was made during a Westminster meeting of the campaign group that repeatedly descended into angry shouting matches.

The Hornsey and Wood Green MP Catherine West said if the government brought forward a proposal for air strikes in Syria, Labour would ask Stop the War for their views.

The event was hosted by shadow development secretary Diane Abbott who has made clear her opposition to future strikes.

Labour's shadow foreign secretary Hilary Benn has left open the possibility that he would support military action. Stop the War is opposed to any military action and believes the US is to blame for the lack of a ceasefire in Syria.

Ms West - a member of Mr Benn's team - said:

Ms Abbott opened the meeting in a House of Commons committee room saying its purpose was to spell out a conclusive case against military action. There were frequent interruptions as members of the audience shouted at each other, and those on the stand. At one point Stop the War's Andrew Murray shouted at the veteran campaigner Peter Tatchell: "Sit down you poser." Police officers stood at the door as the room was cleared when the event ended.

Downing Street has blamed an “oversight” after a Remembrance poppy appeared to have been added to an old photo of David Cameron on the 10 Downing Street Facebook profile picture. The photo has since been deleted, but Twitter users including the Huffington Post's Paul Waugh have been highlighting the change.

A Downing Street spokeswoman said there was “an oversight on the picture” and pointed out the photo had now been changed, but would not confirm it had been digitally altered in the first place.

A majority of Northern Ireland Assembly members have voted in favour of same-sex marriage for the first time.

But the motion has fallen due to a DUP petition of concern which requires the proposal to achieve a cross-community majority.

It is the fifth time the issue has been considered by the Northern Ireland Assembly.

Northern Ireland is the only part of the UK that has not passed a law to introduce same-sex marriage.

“The Trade Union Bill is not only an attack on working people and rights at work, but on democracy itself," says Labour leader Jeremy Corbyn. He claims the measures in the bill will make it harder for people to stand up for themselves and pledges that Labour would reverse it if it won power.

In a speech at a rally outside Parliament tonight in protests at the plans, which include a new threshold for strike ballots, she will say:

Caroline Lucas, the party's only MP, has said that if the bill becomes law, she is prepared to take “non-violent direct action to resist it”

Speaking in the Commons, former Labour housing minister John Healey has said he regretted not building enough houses during his years in government.

Speaking in the Housing Bill debate in his current role as shadow housing minister, he said the lack of house building was also a flaw in the current bill being debated.

He was then asked whether he regretted the economic crisis in 2008. He said: "There were failings in the banking regulations in this country and every other country. What I do regret is that perhaps our ministers listened too hard to the party opposite that were urging us to cut the regulation of the banking sector."

Work and Pensions Committee chairman Frank Field has written to George Osborne asking him to publish analysis of the impact of tax credit cuts.

The Labour MP is seeking a "detailed breakdown" of the effect on family incomes over the first five years of the policy being enacted.
