Jeremy Corbyn provoked a heated row with Labour MPs this evening after he hired a former Sinn Fein member of staff to join his office.

Jayne Fisher, the former-head of Sinn Fein’s London office, is understood to be joining the Labour leader’s team as head of "stakeholder engagement" in January.

Labour MPs have reacted furiously to the news and accused Mr Corbyn of undermining his position by reminding voters of his support for the Left-wing nationalist party.
