Nigel Adams: he’s said to be a Boris Johnson ally – at least, that’s the reason we’re being given for his sudden resignation as an MP.

So it is an exodus, then.

Here‘s the BBC:

Nigel Adams, MP for Selby and Ainsty, has stood down but did not say why.

Mr Adams, a Cabinet Office minister without portfolio under Mr Johnson’s government, had previously announced he would not be standing at the next general election – but has now brought that decision forward.

In a tweet announcing he was going immediately he said Selby Conservatives had selected a new parliamentary candidate on Friday.

It means there will be another by-election. That’s three the Tories have to manage since the beginning of Friday, including Johnson, Nadine Dorries, and now Mr Adams, who is said to have been a Johnson ally.

The Conservatives can ill afford to waste time, money and effort on by-elections when they’re struggling with the economy, the cost of living, and public opinion.

And who knows how many more resignations there will have been by Monday morning?
