Ukip's Steven Woolfe is in a "life-threatening" condition following an altercation with fellow party MEPs in Strasbourg.

Mr Woolfe, who turned 49 today, was taken ill after walking out on a vote at the European Parliament.

Woolfe, who declared on Wednesday his intention to run as party leader, was reported by Nigel Farage to be in a "serious" condition upon being taken to hospital.

Fellow leadership contender Raheem Kassem tweeted that he believed Woolfe was in a "life-threatening" condition.
