The SNP have tweeted:

I will be putting in an Early Day Motion tomorrow. 7 words. 'This House believes Dominic Cummings must go'.

OK, with an 80 majority the PM is unlikely to lose, but the MPs will be well aware that their vote will be referenced come the next election. They will find themselves somewhat torn, having seen their own emails from constituents and reading that a "Good Morning" poll says 79% of people think Cummings should go.

I am sure most will back the PM, but they will all be very uncomfortable about where that could end up for them personally.

The most entertaining would be if Johnson lost the vote, but ignored it, as he is entitled to under the rules.
