After that car-crash press conference @BorisJohnson has no option but to sack his chief adviser. It is now beyond doubt that Dominic Cummings broke multiple lockdown rules, possibly on multiple occasions.

There was no apology and no contrition for his behaviour – and now, following this unrepentant press conference, there are no excuses left. He has done nothing but double down on the double standards he has displayed and which millions of people across the UK are furious about.

Let’s be clear there is nothing about Mr Cummings that is exceptional except his complete inability to realise he broke the rules. The Prime Minister has no option but to sack him. His failure to do so so far is a gross failure of leadership.
