Jeremy Corbyn is embroiled in a racism row after being criticised by one of his own front-benchers for the way he has treated black female MPs.

Chi Onwurah, the shadow minister for culture and the digital economy, said she would have taken the Labour leader to a tribunal “in any other job”.

In January the Labour leader gave Thangam Debbonaire, a fellow Labour MP, the culture half of her portfolio without informing either woman.
