". Smeeth told the Guardian: "I refuse to be intimidated or scared by anyone who resorts to this appalling racist and threatening abuse and they alone are responsible for their actions. But let's be clear: as leader of the official opposition and the head of my party, Jeremy Corbyn has a responsibility to lead and that means more then telling MPs to ignore abuse.

"He needs to name and shame his supporters who are perpetuating this hate and make it clear they are not welcome in our party if they have such abhorrent views."

In June the MP walked out of a press conference for the launch of an independent review into antisemitism in the Labour party that was hosted by Corbyn and its author Shami Chakrabarti. Smeeth had been accused by a Corbyn supporter of colluding with the Daily Telegraph in a row over leaflets criticising MPs opposed to his continued leadership of the party.

The MP said later: "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."
