This is not a drill. Boris Johnson is in charge of the country this week. We repeat this is not a drill.
Downing Street has revealed Johnson has, for the first time, become the senior duty minister in Whitehall while Theresa May is on holiday.
And of course, Twitter has gone into in a meltdown:

The Foreign Secretary takes over from Chancellor Philip Hammond who was the senior duty minister last week when the Prime Minister began her annual walking holiday in Switzerland.
But for those wondering whether May has handed over the full reins to Johnson, a No 10 spokesman stressed that isn't the case.
They insist May still remains very much in charge of the Government - even though she is out of the country.
"The Prime Minister is very much in charge and is constantly kept abreast of what is going on," the spokesman said.
