Jeremy Corbyn has said he will pursue a a "new way" of dealing with the party's backlog of anti-Semitism cases as he faces a crunch meeting with his Shadow Cabinet.
The Labour leader said his party is "not an anti-Semitic party" as he said he would put a new system for dealing with complaints to the party's ruling executive on Tuesday.
He presented two options for speeding up the party's complaints process.
Under his preferred option the most serious of cases would be referred to a special panel consisting of the party's general secretary and NEC officers who would have the power to expel the member - allowing for more rapid action.
Mr Corbyn added: "One anti-Semite is always one too many.
"I also know that some complaints have taken too long to deal with. This is not good enough.
"Our members don't want to share their party with anyone who is racist - and they want to be able to demonstrate there is no place for anti-Semitism among them."
He told the shadow cabinet: "It is wrong to deny there is anti-Semitism in the Labour Party.
"And those who deny that it does exist are part of the problem. We have to stand for a serious, anti-racist, inclusive socialism."
But a source close to the Jewish Labour Movement said: "The NEC officers are creatures of the leadership.
"They will do whatever LOTO tells them.
"That's why they voted 4-1 not to see the EHRC submission even though it was made in their name.
"They're Unite nodding heads."
In a statement issued after the meeting, Labour's Shadow Cabinet said: "The Shadow Cabinet is committed to defeating antisemitism and all forms of discrimination, including through greater education in our movement.
"We commend the General Secretary and party staff on improving the complaints and disciplinary processes within the party.
"As part of tackling antisemitism, the shadow cabinet has today supported the proposal for summary exclusion outlined by the Labour leader, which he will put to the National Executive Committee tomorrow.
"The shadow cabinet also supports the proposal to introduce independent oversight of our processes, and will continue to seek to engage with Jewish community organisations to build confidence."
Labour general secretary Jennie Formby updated the shadow cabinet on disciplinary cases so far this year.
There have been complaints against 625 members relating to anti-Semitism, around 0.1% of the party membership.
There were also complaints about 658 people who are not in the party.
In 28 disciplinary cases concluded by the National Constitutional Committee (NCC) in the first six months of 2019, eight members were expelled, three received an extended suspension and four received a warning.
One member received no action as the NCC found the charges to be unproven and 12 left the party after being referred to the disciplinary body.
The National Executive Committee (NEC) anti-Semitism panels referred 97 members to the NCC in the first six months of 2019, issued 41 with formal warnings and 49 with a "reminder of conduct".
Three cases were closed as the full evidence suggested no further action should be taken.
