Jeremy Corbyn supporters have been expelled from the Labour party for making threats to "cut Tony Blair's eyes out and set him on fire", branding sitting MPs "traitors" and publicly declaring their support for Ukip and the Green party, according to a leaked document.

It follows accusations by the Labour leader and his campaign manager John McDonnell of a "purge" of pro-Corbyn supporters for trivial reasons which sparked a row with Labour staff.

A source close to the party's ruling body accused Mr Corbyn of " demeaning" the Labour party and the leadership contest by claiming that his supporters are being purged without explanation last night.
