Iain Dale: The tragi-comedy of the collapse of Change UK

Plus: Sympathy for the Downing Street SpAds. The case for chemical castration. And: my interviews with the Tory leadership candidates.

Not only is Change UK-TIG unpopular, it is poorly equipped to deal with failure

No strategic judgement, no grassroots depth, no clear command structure, no unifying belief system, and a bunch of fractious personalities make for big trouble.

Where does the Liberal Democrat revival leave Change UK’s cursed campaign?

A lethal combination of strategic incoherence and operational incompetence has seen the Remain wave pass the would-be mould-breakers by.

TIG picks up two MEPs – and walks straight into a left/right argument as a result

It’s the classic small party dilemma – do you accept recruits and defectors, even when they come with baggage?

James Frayne: “Vote for change and Chuka” is laughable. The new party’s candidates come straight out of central casting.

Change UK are not the problem for the Conservatives. Rather, it is their own change narrative is ultimately weak.

Corbyn won’t attend a meeting with Umunna. But here’s who he will meet.

Hamas, Hezbollah, the IRA, Assad, Maduro, dodgy Czech ‘diplomats’, Iranian propagandists….the list goes on.

Chloe Westley: The EU, the Commons – and last week’s votes. The people should fire the MPs who won’t follow their instructions.

I believe that the actions of politicians over the last two years have seriously weakened trust in the system.

The Independent Group. A problem for the Conservatives but a danger for Labour.

Tory difficulties are bound up with Brexit. Labour’s stretch wider, and are part of wider ones for social democratic and democratic socialist parties.

Can Labour out-Europhile The Independent Group with this second referendum pledge?

It rarely worked for the Conservatives when they tried to out-UKIP UKIP.

WATCH: Gardiner says Umunna quit because “he knew he could never be the leader of the Labour Party”

The Labour spokesman also calls his former colleague out for not offering the people of Streatham a ‘people’s vote’.

Rachel Wolf: On policy, it’s not the Independent Group that’s driven to the margins. It’s the Conservative Right.

The new group’s platform is not very inspiring. But its biggest problem is it they won’t be very different from the Conservatives’.

Iain Dale: Welcome to the Monster Raving Soubry Party

Plus: In news elsewhere, a luxury women’s health spa in Belgravia – with annual membership fees of £5,500 – this week blamed Brexit for its closure.

So you’ve decided to set up a new party. Eight tips from UKIP’s experience.

The SDP analogies are all wrung dry. But nobody has looked at what a more recent insurgency can teach the new outfit.

The moment will come for Umunna to face the voters of Streatham in a by-election. But not yet.

He and others should resign their seats, and then face their voters if they wish, when they join a new political party – but not before.

Yes, our system favours the established parties. But it is not invulnerable to change. This could be the start of a breakthrough.

The failure of the SDP by no means proves that a new movement of this kind is doomed to failure.
