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.
So far, eight Labour MPs and three Conservative MPs have quit their parties and joined forces as The Independent Group.
Here we answer some of your biggest questions about what is now the fourth-largest group in Parliament.Are there going to be by-elections?
In a video posted on Twitter, the Labour leader said it was the "decent and democratic thing to do" because the MPs wanted to "abandon the policies on which they were elected".
If an MP changes or leaves The Party they were elected under, there does not automatically have to be a by-election.
This is because at the ballot box voters chose the individual they wanted as their MP, not The Party they wanted running the country.
However, the defectors could trigger a by-election by resigning as MPs.
They could then immediately stand for election in the same constituency - That 's what in 2016. (He lost his 23,015 majority and was ousted).
But these MPs don't want to face a by-election right now.
Voters can also call for a petition to recall their MP - and trigger a by-election.
But this can only happen under specific circumstances, such as an MP being convicted of an offence and receiving a custodial sentence. And none of these conditions apply to The Members of The Independent Group.
Since they launched, they have been crowd-funding via their website.
However, they they intend to do so anyway and will publish all donations over £7,500 alongside donors' names.
If The Group registers with The Commission , the MPs would be entitled to - That is funding given to opposition parities in Parliament to support them in their parliamentary business, expenses and costs of running.Which one is the leader?

But he has been named as The Group 's spokesman and said: "We are not a Political Party and therefore do not have a leader, But the roles and responsibilities we have assigned recognise That all The Members of our group have The Right to be heard and a responsibility to provide leadership. "
Notably, there is no sign of Brexit on The List , although it mentions "maintaining strong alliances with our closest European and international allies on trade, regulation, defence, security and counter-terrorism".
On inequality, The Group calls for the "barriers of poverty, prejudice and discrimination" to be removed - and says everybody should make a contribution to society.
It also says it believes That :

The Independent Group have bonded over their shared desire to prevent a no-deal Brexit.
Some of them have been working together for months as members of the cross-party People's Vote campaign for another EU referendum.
Former Conservative Heidi Allen said they had been "clinging to each other like on a shipwreck" during the "chaos" of Brexit, and had begun to realise they had "quite a lot in common" with each other.
They do come from different sides of the traditional political Divide - and there may be tensions over issues such as austerity and the privatisation of public services.
Last year, Luciana Berger , then a Labour MP, blamed austerity for having a "devastating cumulative impact" on her constituents and Chuka Umunna has said austerity "failed" and "disproportionately hit the poorest".
Asked on BBC Newsnight if they could all agree on issues such as this, Ms Allen said "probably not, But it doesn't matter because this is a fresh start".The Group shook hands as they sat down together for the First Time in The Commons
With 11 members, they are the fourth largest group of MPs - behind the Conservatives, Labour and the SNP, and equal to the Lib Dems.
"The defections change not just the official arithmetic in Parliament, But its alchemy and atmosphere. "
If they were to surpass the SNP's Westminster cohort - which would require 24 more MPs - The Party would become Parliament's third largest.
In terms of the parliamentary votes, it won't. These MPs were defying their former party whips on Brexit long before they quit.
