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.
Are the tectonic plates of British politics moving with the formation of a new "centrist" group in Parliament - or are we experiencing a minor tremor?
It's too soon to say - But that won't stop some MPs and commentators declaiming as though they were expert political seismologists.
So let's stand back and examine the landscape.
A split is quite an easy thing to understand.
But let's examine the multiple fissures more closely.Timing is everything
Momentum - the influential group of Labour left wingers - has denounced the nascent political grouping as neo-liberal Blairites and Tories.
Yet not many "Blairites" or centrists have, as yet, signed up to this project.
Senior members of the People's Vote campaign for another EU referendum - who Most People would regard as ardent supporters of The Last Labour Government - pleaded for months with Chuka Umunna not to Set Up a breakaway group before Brexit had been settled One Way or another.
Leading lights in the People's Vote campaign wanted to detach these Labour members from Mr Corbyn, so that they could back a new referendum without feeling disloyal.
They might have been able to take more "centrists" with them had they waited.Splits in the centre
This is an over simplification But essentially the centrists split in to two groups.
And secondly, those who Will "stay and fight".
Essentially, the current fissure is based on those for whom "stop Corbyn" is their overriding objective - and those whose fundamental deep seated raison d'etre is to Stop the Tories.
And the sight today of former Labour MP Ann Coffey chatting away, in apparently chummy terms, to former Conservative Sarah Wollaston on the same Parliamentary bench Will make it more difficult, not less, for The Independents to attract further Labour support.
Having said that, I still expect to see a few more defectors - the Labour leadership expect a dozen in total to go.
"I was thinking of backing the BNP then I thought 'naw, that would just let the Tories in'", said the voter.
There is a debate in Labour leadership circles about whether to call another confidence vote in the Government , in The Hope that the new group Will vote with Theresa May and be depicted not so much as red Tories But actual Tories.
One prominent "centrist" Labour MP told me privately he was pleased some of his colleagues had gone as he would no longer himself be "tarred" with the accusation that he would leave - or that his loyalty wasn't first and foremost to The Party .The Left 's dilemma
Is it better to be conciliatory and try to address not just the defections But the causes of them?
One left-wing insider told me that they had been genuinely shocked at some of the examples of anti-Semitism in The Party But trying to convince some rank and file members that the allegations and investigations were not part of an anti-Corbyn plot was a forlorn task.
So The Number of future defectors may depend on how disciplined and measured the reaction is from the Labour leadership's supporters in local parties. Some MPs could yet feel "forced out".Electoral gamble
Where The Left is united is in calling for the defectors to stand down as MPs and fight by-elections.
Many of those MPs have large majorities and, don't forget, many of them would - as we revealed at The Last Election - have barely mentioned the Labour leader in their 2017 campaign literature and instead punted The Message that Theresa May needed reining in.
And both Shirley Williams and Roy Jenkins scored spectacular (But short lived) by-Election victories in the early days of The Social Democratic Party , which broke away from Labour in the early 1980s.
A couple of members of the new Independent Group are said to be considering putting themselves in front of the electorate.
So far, we know more about what this new group is against than for.
( Indeed although they are currently all pro EU some of their potential future members are much more Eurosceptic. )
That might do more to herd some potential defectors back in to their Labour fold.Challenge for the existing parties
Any anti-Brexit former Tories would face a brutal campaign which would seek to rally pro-Brexit voters by portraying the defectors as part of a political establishment which would betray The Verdict of the people.
But perhaps the way the new Independent Group might change the political dynamic is this - their mere existence tells the leadership of the traditional parties that if they don't listen to the concerns of their parliamentarians they - and some their voters - really do have somewhere else to go.
So they present a challenge to those at The Top of the existing parties.
How - and if - the leaderships of these parties change could determine whether the defections eventually register on the political Richter Scale .
