Labour party split: Chuka Umunna, Luciana Berger, Joan Ryan and the MPs who have quit the party
Eight Labour MPs have quit the party to become part of the new Independent Group.
Seven told a press conference on Monday they had left to sit as part of the new faction in the Commons.
They were followed by Joan Ryan who announced her departure late on Tuesday.
The initial MPs who quit Labour were: Chuka Umunna, Luciana Berger, Chris Leslie, Ann Coffey, Angela Smith, Gavin Shuker and Mike Gapes.
They said "none of today’s political parties are fit to provide the leadership and direction needed by our country."
Here are the MPs who quit Labour today:
Chuka Umunna
Chuka Umunna called for a change in politics to make it "fit for the here and now".
He said the "established parties are simply not up to the challenge" and called them "deeply divided".
"They don't represent the complex tapestry which is modern Britain," he said.
"We have got to change our politics again.
"We invite you to leave your parties and help us form a new consensus on a way forward for Britain."
He has long promoted calls for a second referendum on Brexit and encouraged this stance.
The Streatham MP was asked on Thursday whether he would quit Labour, should Jeremy Corbyn refuse to back a second referendum, and said: "When I joined the Labour Party, I intended to be a member on my death-bed. Ultimately whether we keep the party together is a matter for the leadership.
"If the leadership of either party reverts to making party political decisions instead of pursuing the national interest, then they will never, ever be forgiven."
Luciana Berger
An outspoken critic of the handling of anti-Semitism within Labour ranks, Luciana Berger is also one of those who left.
She has frequently spoken negatively of Jeremy Corbyn's leadership and required a police guard when attending the Labour party conference in Liverpool last year follow vicious threats made to her online.
As she announced her resignation, she said: "For my part, I have become embarrassed and ashamed to remain in the Labour Party.
"I have not changed. The core values of equality for all, opportunity for all, anti-racism against all and social justice - the values which I hold really dear and which led me to join the Labour Party as a student almost 20 years ago - remain who I am.
"And yet these values have been consistently and constantly violated, undermined and attacked, as the Labour Party today declines to my constituents and our country before party interests.
"I cannot remain in a party which I have come to the sickening conclusion is institutionally anti-Semitic."
Recently she was on the brink of facing a no confidence motion from her local Labour faction, though this was withdrawn after she was strongly defended by prominent Labour colleagues.
When the confidence vote was announced, she said: "I have made no secret that, as a Jewish woman representing a city with a Jewish community, I have been deeply disturbed by the lack of response from Jeremy Corbyn as party leader and many in the wider leadership to the anti-Semitism that stains our party."
Gavin Shuker
The 37-year-old Labour MP for Luton South has previously spoken of considering his position within the Labour party.
Announcing he was leaving on Twitter, he said: "At a national level, I hope you'll agree that politics, as it is, is broken. None of the parties are providing the leadership that we need at this moment of crisis, and you've been trying to tell us this for a long time - not just since Brexit. That's why my hope is that the actions I've taken today, alongside others, will enable us to change politics, together."
Previously he quit the frontbenches upon Jeremy Corbyn's selection as leader.
At the time of leaving his former position of shadow interational development minister, he cited "political differences" for quitting the front bench.
He has continued to be critical of Mr Corbyn and also previously faced a confidence motion from his local Labour group, which was unsuccessful in ousting him.
Angela Smith
Angela Smith has spoken of her desire for a second referendum and her disdain over her party's stance on Brexit.
She claimed earlier this year she was turned away from the Labour HQ when she tried to deliver a petition calling for a second Brexit vote.
She previously told Channel 4 news "Labour MPs are being pushed to the very edge by the attitude of the leadership on key issues such as Brexit, anti-Semitism".
Ms Smith has represented Penistone and Stocksbridge since 2010 and prior to that was MP for Sheffield Hillsborough.
Mike Gapes
Mike Gapes has previously spoken out on anti-Semitism in the Labour party.
He said it was a "fantasy" that Jeremy Corby believes he can renegotiate Brexit.
Announcing his departure, he said: "I am sickened that the Labour Party is now a racist, anti-Semitic party.
"I am furious that the Labour leadership is complicit in facilitating Brexit, which will cause great economic, social and political damage to our country."
He is the MP for Ilford South and has been since 1992.
Chris Leslie
The Nottingham East MP has been critical of the party's stance on Brexit, questioning why it was not backing a second referendum.
The 46-year-old was previously shadow chancellor of the exchequor in 2015.
He previously hinted he could leave the party over the situation.
He told BBC Radio 4's World at One: "My patience is wearing pretty thin with the Labour Party policy on Brexit."
Ann Coffey
Ann Coffey was behind a letter of no confidence in leader Jeremy Corbyn after the Brexit referendum vote.
She is the MP for Stockport and has been since 1992.
Ann Coffey told the press conference: "I thought I would be in the Labour Party for the rest of my life.
"But political parties are not an end in themselves in a parliamentary democracy. The Labour Party has lost sight of this, it is no longer a broad church.
"Any criticism of the leadership is responded to with abuse and accusations of treachery. Anti-Semitism is rife and tolerated."
Joan Ryan
Joan Ryan, who chaired Labour Friends of Israel, announced she quit the party in a Tweet on Tuesday.
She wrote: "After 4 decades, I have made the terribly difficult decision to resign from the Labour Party."
After quitting, the MP for Enfield North said Labour leader Jeremy Corbyn had ignored calls to tackle the problem of anti-Semitism and was not fit to be prime minister.
"We never had this problem in the party before he was the leader. It comes with him, it is part of his politics, I am afraid," she told BBC Radio 4's Today programme.
"We have had endless calls on him to deal with the most virulent, vile anti-Semitism - bullying, abuse and aggression - and he has turned away from doing that."
