It’s never a good look for a politician to have fewer principles than UKIP. When Tory MPs Douglas Carswell and Mark Reckless defected to Nigel Farage’s party, both stood down from their seats and fought by-elections to establish whether their electoral mandates were personal or owed to the party. Both of them won. (Though both men subsequently lost at general elections and Reckless has now returned to the Tories.)

The seven Labour MPs who resigned from the party today have no such honour and no such respect for the electorate. They’ve quit the party but not their cushy and lucrative jobs as opposition MPs, and will bring about absolutely no practical difference other than sitting a few feet further to the left in the Commons voting exactly the same way as they did before.

Labour MPs already regularly rebel against the whip anyway – just last week 40 of them broke ranks to back an SNP amendment on Brexit. So nothing will be achieved by Chuka Umunna and six people nobody in the real world has ever heard of splitting under the meaningless umbrella name “The Independent Group”, whose claim that “politics is broken” was neatly illustrated by its website at their big launch moment.

The seven claim that Labour values no longer represent them, yet they’re happy to remain in the seats that Labour’s manifesto and brand secured for them. Nor do they wish to stay in the party and fight for the values they think it should have. They’ve chosen the most cowardly, meaningless form of protest possible: keep cashing the paycheques but carp from the sidelines.

There are already three MPs elected as Labour but who now sit as nominal “independents” – Frank Field, John Woodcock and Ivan Lewis – and the fact that most people’s reaction to that fact will be “Who?” tells you all you need to know about the impact and power of not-actually-resigning “resignations”. Jeremy Corbyn’s reaction will be a shrug. Oh no, fewer Blairites in his party. Not the briar patch, Brer Fox!

And Theresa May? Theresa May won’t even notice. Why would she? TIG poses no kind of threat to her. The idea that any MPs from other parties are going to change their vote on anything just because there’s a new gang of would-be cool kids in the cafeteria who’ve given themselves a name is laughable in its tin-eared arrogance.

Indeed, mention of Brexit – the only political issue anyone in most of the UK cares about right now – was startlingly conspicuous by its near-total absence from the group’s press conference. Instead there was an almost endless parade of petty personal gripes and grievances in which the Labour Party was decried as a shambolic, racist, anti-Semitic entity posing a mortal threat to the nation’s politics – yet not one bad enough to actually take a stand against at the ballot box.

The 400-odd words we’ve written here already indulge the TIG “rebels” with far more attention and significance than their empty, craven gesture merits. So we won’t waste your time and ours with any more.
