According to daily The Times, the British Labour party’s annual onference is at risk of cancellation following the party’s decision to boycott the conference security company G4S because of its links with Israel.

The Labour National Executive Committee voted to ban G4S, its regular provider, citing the company’s work in Israel as a key reason.

According to The Times, the party has failed to secure services from a new security company after cancelling its deal with G4S. Home Office and police warned they could shut down the conference if an alternative were not found.

The party is understood to have approached five companies, three of which declined the contract and one which withdrew its bid.

The news came as a new row over anti-Semitism within Labour intensified as it emerged that friends of party leader Jeremy Corbyn and Shadow Cabinet members have compared Israel to Islamic State terrorists, The Daily Mail reported.

Communities spokesman Grahame Morris wants British Jews who serve in the Israeli army to be treated as suspected terrorists while Justice spokesman Richard Burgon has urged MPs and party members to quit the Labour Friends of Israel group, declaring: '‘Zionism is the enemy of peace.’'

Corbyn was himself accused of comparing Israel to ISIS when launching the inquiry into anti-Semitism, overshadowing the event and its contents.

The revelations follow the row over a peerage for Shami Chakrabarti, who produced a controversial report concluding that the party ‘‘is not overrun by anti-Semitism’’.

Chakrabarti, a human rights lawyer, was given a peerage by Jeremy Corbyn despite having been been accused by a senior Labour aide of ignoring explosive evidence in her inquiry into anti-Semitism within the party.

Jonathan Sacerdoti, leader of the Campaign Against Anti-Semitism, said: ‘‘A web of evidence and connected actions is revealing a party engaging in anti-Jewish activity not by accident but by design.’’
