Nearly half of Labour members believe Corbyn has handled antisemitism crisis 'well'

Meanwhile, 27 per cent of members agreed that Mr Corbyn should "step down now" - up from 12 per cent in March 2018. 

Some 12 per cent said he should resign "before the next general election", a slight rise on the 10 per cent recorded last time.

On Brexit, the YouGov poll found that just 42 per cent of members believe Mr Corbyn has handled Labour's position in the EU either "very" or "fairly" well, while 56 per cent said Mr Corbyn had dealt with Brexit "very badly" or "fairly badly".

However, more than 80 per cent said they still thought the Labour leader had the "right priorities for the country".

The findings came ahead of a crucial Shadow Cabinet meeting on antisemitism on Monday afternoon, a separate meeting with Labour MPs in the evening, and a meeting of the ruling National Executive Committee (NEC) on Tuesday.

Deputy leader Tom Watson has tabled proposals for automatic expulsion of anyone found guilty of antisemitism which will be voted on at a meeting of Labour's governing body, the National Executive Committee.

But HuffPost reported Mr Corbyn and his allies were tabling their own proposal where the current specialist NEC panels would be given unprecedented power to expel antisemities, rather than referring cases to Labour’s quasi-judicial National Constitutional Committee (NCC).

The NCC can spend months, and in some cases years, determining its decision on expulsion and the new option - understood to have the backing of key Left members of the NEC - is aimed at sending a strong signal in the worst examples of antisemitism.
