Christopher Michael Leslie is a British Labour Co-operative politician. He has been the Member of Parliament for Nottingham East since 2010. In 2015, between May and September, he served as Shadow Chancellor of the Exchequer in the shadow cabinet of acting Labour leader Harriet Harman.
Seven MPs have walked out in protest at the Labour leader's handling of anti-Semitism and Brexit.
One of the seven, Chuka Umunna , said "a lot of Labour MPs" could follow suit, together with Tories "demoralised by the UKIPisation of their party".
Deputy Labour leader Tom Watson has warned his party could see more defections if it did not change.
He said Labour had to do more to tackle anti-Semitism and he also urged Mr Corbyn to reshuffle his shadow cabinet to reflect a wider range of MPs.
The seven MPs - Mr Umunna, Luciana Berger , Chris Leslie , Angela Smith , Mike Gapes , Gavin Shuker and Ann Coffey - quit Labour in protest at what they said was a culture of "bullying and bigotry" in The Party and frustration over the leadership's reluctance to back another EU referendum.
He urged members of all parties to join them in building an "alternative" to the current two party system, which he said was "fundamentally broken".
The BBC has been told two Conservative MPs are thinking of joining the new Independent Group in Parliament.
Mr Umunna refused to speculate on who they could be But he added: "There are a lot of Labour MPs wrestling with their conscience on this issue But also Conservatives who have become demoralised by the UKIPisation, if you like, of the Conservative Party . "
A Number of Conservative MPs are at the centre of rumours about joining the new group.
Sarah Wollaston , a supporter of the People's Vote campaign for another EU referendum, along with the seven Labour defectors, has warned about former UKIP members joining local Tory parties and the pro-Brexit European Research Group (ERG) pushing The Party to The Right .
For now though that is way off. And this is first and foremost about the Labour Party - The Seeds of the splinter sown More Than three years ago, bearing Bitter Fruit just when Parliament's biggest decisions over Brexit are about to be made.
"It is clear that Brexit is pushing both parties to The Brink , it is clear that anti-Semitism has taken root in our party. "
However, shadow foreign secretary Emily Thornberry that the resignations were a "distracting and divisive exercise".
Shadow business secretary Rebecca Long-Bailey told BBC Radio 4 's Today programme Labour MPs had to "listen to each other".
But she added: "Equally, I think we also have a duty to unify and make sure that we provide a force for change within Britain. "
