Jewish Labour donor to challenge Corbyn leadership decision in High Court

Commenting on the time frame for his challenge to the National Executive Committee’s decision, Mr Foster said: “If the case is heard – and I think it will be heard – the matter will be adjudicated in days not weeks.”

Tom Watson, Labour’s deputy leader, said Mr Foster’s challenge was “very unhelpful and destabilising to the Labour Party”.

Last October Mr Foster heckled Mr Corbyn at the end of his address at a Labour Friends of Israel session at the party conference.

Mr Foster, angry that the Labour Leader and long-term pro-Palestinian campaigner had not mentioned Israel by name during his speech, shouted “say the word Israel! Say the word Israel!” at Mr Corbyn.

In a piece he wrote for the Daily Mail earlier this year, Mr Foster sharply criticised Mr Corbyn’s “crass, hateful and ignorant support” for those within Labour who “blend Israel and Zionism into the supposed demagoguery of the classic Jew, an all-controlling malevolent demon”.
