Labour MP Wes Streeting said just three months ago that the party’s leader, Jeremy Corbyn, wouldn’t make a good prime minister.

Now, he’s been filmed at the Pride in London celebrations singing the incredibly catchy “Oh Jeremy Corbyn” chant.

It appears he does so of his own free will, and he looks pretty happy about it:

He has since taken to Twitter to reassure concerned voters that he's okay.

Everyone together now.
