Senior MPs on both sides of the green benches for Andrew Mitchell to be reappointed to the Cabinet after a police officer admitting to falsely claiming to have witnessed the 'plebgate' row between the former Chief Whip and officers:
Prominent Labour MP Tom Watson has admitted to an "embarrassing mistake" tonight after voting the wrong way on changes to rules surrounding Fixed Odds Betting Terminals (FOBTs) - an issue he had personally led a campaign on.
In a blog post after the result, Mr Watson admitted this was the worst time to make such a mistake - but insisted it was "bound to happen" at some point in his Commons career.
He said: "I voted the wrong way as my head said put the cross in the 'no' box but my hand put the cross in the 'yes' box.
"On most days few would notice this act of tiny rebellion. Except this was the day in which I made the front page of the Daily Mail, leading the campaign against FOBTs.
Mr Watson was initially even more shocked after first thinking the vote had been lost by only one vote - joking he almost "jumped in the Thames".
An internal report initially found concerns over the selection of a Labour candidate for the 2015 General Election in Falkirk.
After allegations were made that the Unite union was involved in selection-fixing in the constituency, the selection process was postponed and leader Ed Miliband hit out at the union's general secretary Len McCluskey.
It was the ensuing bitter public dispute between the pair that led Mr Miliband to propose reforms to Labour's historic links with the trade unions.
Tom Watson - for whom the Unite-backed candidate Karie Murphy worked - quit as the party's General Election co-ordinator at the height of the dispute.
Earlier this week the GMB union, which supported Mr Miliband's leadership bid, announced it was slashing its affiliation funds to the Labour Party from £1.2 million to £150,000.
The Labour MP Tom Watson, who quit as the party's election co-ordinator during the "media frenzy" over allegations surrounding the selection of the prospective parliamentary candidate for Falkirk, has tweeted:
At the time, the shadow defence secretary said Unite had "well and truly overstepped the mark" in the constituency where there had "clearly been some external interference".
An internal inquiry has said there was no evidence involving Karie Murphy, who works for Mr Watson.
Labour's former General Election co-ordinator Tom Watson has pledged to "fight very hard" to retain the party's links with trade unions after the GMB union announced it was slashing its funding.
Mr Watson, who was involved in the selection of Labour's election candidates, resigned his shadow cabinet position over the Falkirk row.
He wrote on his blog: "If this is the beginning of the end of that historic link, it is a very serious development that threatens a pillar of our democracy that has endured for over one hundred years.
"Some will scoff but they are fools to do so. That party card stands for something more than confirmation that an annual direct debit has been processed."
Labour MP Tom Watson has questioned whether Home Office ministers were informed of the decision to arrest the partner of a Guardian journalist and called it "an embarrassment to the Government".
He told the BBC: "What I think we are going to see is this is sort of the intelligence services overstepping the mark - they are clearly trying to intimidate Glenn Greenwald - and that's an attack on journalism.
"I think politics needs to intervene to make sure it doesn't happen again."
Tom Watson has resigned from his shadow cabinet role as general election co-ordinator, he has said on his blog.
An MP has called for police action after Rupert Murdoch was apparently recorded telling journalists he regretted the level of cooperation over phone-hacking and illegal payments.
Labour MP Tom Watson called for police to question Mr Murdoch over the alleged comments, telling Channel 4 News:
Labour's election co-ordinator Tom Watson said his party enjoyed a good night in the local elections and South Shields by-election.
Speaking to the BBC Radio 4 programme, Mr Watson said "We had a good result on what we have seen so far, to get 50 per cent of the vote in South Shields, to win back the mayor in Tyneside, to make progress in the Westminster battleground seats within counties is good for us.
"In the Westminster battleground seats, places like Harlow, Hastings, Stevenage, Cannock, the Westminster seats we lost in 2010 and we need to win back in 2015, they are coming back to Labour in quite big numbers."
The MP for West Bromwich East said Labour leader Ed Miliband had been consistently told by voters that they felt a sense of "powerlessness" when it came to politics and its ability to change their lives.
"At the heart of this is economic failure, they feel the Government plan is not working and they feel the job of the Labour Party is to convince people there is a better way, that we can address this squeeze on living standards and give people more hope," he said.
