How Labour's most rebellious member went from being an outsider to its newest leader

In the space of three months, Jeremy Corbyn has gone from fringe member of the UK opposition Labour party to leading it.

Corbyn won the leadership vote by a landslide on Saturday with 59.5% of the vote, beating Tony Blair's haul in 1994.

It's a strange turn of events for a man who has spent a lot of his political career fighting his own party.

He's been called "unelectable" because of his radical policies, which include giving people the chance to opt out of spending their taxes on the military and renationalising the major utilities.

Here are a few choice moments from his life and career that might go some way to answering the question of just who Jeremy Corbyn is.
