The Labour Party is not a "safe space for British Jews" under the leadership of Jeremy Corbyn, according to a Jewish MP.

Ruth Smeeth, elected as MP for Stoke-on-Trent North in 2015, added that the left-winger was "unfit" to lead the party.

Her comments came after she left a Labour event in tears when a party activist accused her of colluding with the Daily Telegraph against Labour.

The event was held on Thursday to mark the publication of Shami Chakrabarti's inquiry into Labour Party anti-Semitism.

In a separate row from the same media conference, Jeremy Corbyn appeared to draw a parallel between Israel and the Islamic state.

He said: "To assume that a Jewish friend or fellow member is wealthy, some kind of financial or media conspiracy, or takes a particular position on politics in general or on Israel and on Palestine in particular, is just wrong.

"Our Jewish friends are no more responsible for the actions of Israel or the Netanyahu government than our Muslim friends are for those various self-styled Islamic States or organisations."

The comments drew a furious response from Israeli Labor Party leader Isaac Herzog, who tweeted: "Corbyn's suggestion of moral equivalence between Israel and ISIS is outrageous, unacceptable, and a betrayal of global Labour values. Corbyn's views represent a consistent hatred of Israel. Like the notorious Ernest Bevin failed, so too will Jeremy Corbyn."

On Thursday afternoon, Smeeth revealed she had contacted Labour Party bosses to lodge a formal complain against Corbyn.

She said in a statement: "This morning, at the launch of the Chakrabarti Inquiry into antisemitism, I was verbally attacked by a Momentum activist and Jeremy Corbyn supporter who used traditional antisemitic slurs to attack me for being part of a 'media conspiracy'.

"It is beyond belief that someone could come to the launch of a report on antisemitism in the Labour Party and espouse such vile conspiracy theories about Jewish people, which were ironically highlighted as such in Ms Chakrabarti's report, while the leader of my own party stood by and did absolutely nothing."

Smeeth continued, describing the Labour Party as not safe for British Jews under Corbyn's leadership.

She added: "People like this have no place in our party or our movement and must be opposed. Until today I had made no public comment about Jeremy's ability to lead our party, but the fact that he failed to intervene is final proof for me that he is unfit to lead, and that a Labour Party under his stewardship cannot be a safe space for British Jews. I have written to the general secretary of the Labour Party and the chair of the parliamentary Labour party to formally complain about this morning's events."

"No-one from the Leader's office has contacted me since the event, which is itself a catastrophic failure of leadership. I call on Jeremy Corbyn to resign immediately and make way for someone with the backbone to confront racism and antisemitism in our party and in the country."

However, Corbyn released a statement on Thursday afternoon saying he would not stand down and the Labour Party had to remain united to defeat the Conservatives.

He said: "United we stand, divided we fall is one of the oldest and truest slogans of the labour movement. After last week's referendum, our country faces major challenges. Risks to the economy and living standards are growing. The public is split.

"The government is in disarray. Ministers have made it clear they have no exit plan, but are determined to make working people pay with a new round of cuts and tax rises.

"Labour has the responsibility to give a lead where the government will not. We need to bring people together, hold the government to account, oppose austerity and set out a path to exit that will protect jobs and incomes.

"To do that we need to stand together. Since I was elected leader of our party nine months ago, we have repeatedly defeated the government over its attacks on living standards. Last month, Labour become the largest party in the local elections. In Thursday's referendum, a narrow majority voted to leave, but two thirds of Labour supporters backed our call for a Remain vote.

"I was elected leader of our party, for a new kind of politics, by 60% of Labour members and supporters. The need for that different approach now is greater than ever. Our people need Labour Party members, trade unionists and MPs to unite. As leader it is my continued commitment to dedicate our party's activity to that goal."
