A mere hour after Jeremy Corbyn was elected leader of the Labour Party in the UK, republican presidential candidate, Donald Trump proved he truly has a firm grasp of British politics after he was duped into tweeting a picture of Corbyn - convinced the newly elected leader was a fan's father voting for the first time ever..for Trump.

The Twitter user behind the prank, who describes himself as a Labour Party member in his bio, has now christened today "the stupidest day in political history".
It's not the first time the business mogul has been duped on Twitter - he's even retweeted pictures of famous murderers he thought were the parents of fans.
Not a single incorrect tweet where Trump made the error has been deleted - even after Twitter users pointed out the real identities.
