French Socialist politician is left fighting for his life after Macron MP hits him with a motorbike helmet when he called him a dirty Arab’

An MP in French president Emmanuel Macron’s En Marche! party has been detained in custody after allegedly putting a rival politician in intensive care by smacking him with a motorbike helmet.

Two police officials explained today that M’jid El Guerrab was being questioned over a fight he had on Wednesday with Socialist Party lawmaker Boris Faure.

It has been alleged in French media that El Guerrab was riding a motorbike in the centre of Paris when he saw Faure – with whom he is said to have fallen out last year – and went over to him.
