It's official. Brexit Britain is an international laughing stock.

Saturday Night Live opened last night's show with a sketch on Brexit, featuring Kate McKinnon as Theresa May, Matt Damon as a 'well rested' David Cameron and Aidy Bryant as, for some reason, Elton John.

The sketch opened with McKinnon adding Mrs May to the list of prominent political figures she's lampooned, dancing with a troupe of policemen and singing "Happy Christmas Britain" to the tune of Stevie Wonder's Happy Birthday.

As the bopping coppers depart, she turns to the camera, saying: "What a dreadfdul week it's been. My Brexit deal is falling apart, I almost got voted out and no-one in the world likes me at all. Yip, dip."

The sound of a brick through a Number 10 window signals the arrival of her first guest, David Cameron - played by Matt Damon. Mrs May introduces him as "the man who called for the Brexit vote, then when it passed, he bounced and left me to clean up his mess. Thankyou so much."

Damon, as Cameron, enters, telling May she looks stressed. He declares he's just been on holiday to the Maldives and advises his beleaguered successor to try it.

(In reality, Cameron usually vacations in Cornwall, Portugal and southern Spain.)

She says she's been a bit busy.

Cameron replies: "Oh, right, Brexit. Gosh, I'm such a knob."

May deadpans that the process has been "a joy."

Then Cameron pipes up with another suggestion: "You know what you should do? You should ...make a deal. Have you tried that?"

"We're working on it, thankyou," comes a weary response.

Cameron adds: "You know what's funny? People hate me - but they really hate you, even though I did Brexit. You've got to laugh."

Theresa May agrees to laugh, before letting out a noise unrecognisable as any form of human laughter.

At this point, Bryant enters as Elton John to distribute presents for no adequately explained reason.

But when May declares "yaaaaas queen", he angrily tells her: 'No! We're not friends and I don't like that."

It transpires that all of the gifts delivered by the hitmaker contain poo.

May goes on to introduce her next guest, Lord Voldemort from Harry Potter, whom she describes as the "one person in Britain more reviled than me."

But the Dark Lord asks her not to lump them together, as "I just can’t have that be the pull-quote from this interview."
