Labour mayoral candidate Sadiq Khan and leader Jeremy Corbyn unite for campaign

Labour leader Jeremy Corbyn and the party's London mayoral candidate Sadiq Khan showed a united front on the campaign trail in north London.

Mr Khan was in Mr Corbyn's constituency of Islington North to canvass voters.

This is the first time they have been seen together since a list describing the mayoral hopeful as "hostile" towards his party leader was leaked to The Times, external and raised during Prime Minister's Questions.

Nick De Bois, chairman of the Tory's Back Zac 2016 mayoral campaign, said the relationship between the men should not affect Londoners.
