Jeremy Corbyn is to share a stage with supporters of the Palestinian militant group Hamas – including an academic who has defended suicide attacks.

The Labour leadership frontrunner will speak later this month at a London conference hosted by the controversial publication Middle East Monitor.

One speaker will be Palestinian-born Dr Azzam Tamimi, who once told the BBC that ‘sacrificing myself for Palestine is a noble cause... I would do it if I had the opportunity’.

Another is Carlos Latuff, a cartoonist who compares Israel to the Nazis and came second in a Holocaust cartoon competition held by Iran in 2006.

Last night senior Labour MP John Mann, chairman of the all-party parliamentary group against anti-semitism, said: ‘These are not people a would-be Prime Minister should be sharing a platform with – and any contact with them should be to challenge them about their vile views.

‘He should be challenging Tamimi about his view that suicide bombings are in some way noble, and some of Latuff’s cartoons are deeply offensive. This sort of event is not where a would-be Prime Minister should be, it’s hugely inappropriate.’

Dr Tamimi claimed he was not advocating suicide bombing after speaking to the BBC in 2004, but backed ‘martyrdom’ three years ago during an event at Queen Mary University of London. The academic, described as a former adviser to Hamas, also caused offence in 2008 during a TV debate with Israeli academic Yossi Mekelberg about the Middle East.

Professor Mekelberg said: ‘We need justice for everyone...’ and Dr Tamimi replied: ‘Justice? You go back to Germany. That’s justice. You turn Germany into your state, not Palestine.’

The militant wing of Hamas has been outlawed as a terrorist organisation by Britain since 2001. Both its military and political wings are on the terror list of the US and the EU.

LABOUR BLOCKS 1,200 VOTING 'INFILTRATORS' Labour has stopped 1,200 people from voting in the leadership race because they are undercover supporters of other parties, it has emerged. Data released by Labour shows the number who paid £3 to register to vote in the contest has more than doubled since May’s General Election. Party staff have been forced to vet new applicants amid concerns over infiltration by hard Left groups trying to secure victory for Jeremy Corbyn. Some 1,200 applications have been rejected – 275 of whom stood in elections for rival parties. Some 214 of those ran for the Greens, 37 for the far-Left Trade Unionist and Socialist Coalition and 13 for the Tories. One is an ex-Lib Dem MEP. Up to one third of new Labour members in some areas are infiltrators – making the election race ‘untenable’, MP Simon Danczuk said last night. A party spokesman said the vetting process was ‘robust’. Mr Corbyn is 32 points ahead of nearest rival Andy Burnham and is on course for a ‘knockout’ victory, a YouGov poll for The Times last night showed. Advertisement

Middle East Monitor is seen as sympathetic to the Muslim Brotherhood, the Islamist organisation founded in Egypt and allied to Hamas.

The publication’s senior editor is Ibrahim Hewitt, who has claimed that adulterers should be stoned to death and gay men receive 100 lashes.

Hewitt runs a private Muslim school in Leicester which was investigated for extremism. He is also a trustee of the charity Interpal, which is accused by the US of sponsoring terrorism.

In February 2013, veteran Left-winger Mr Corbyn and his wife travelled to Gaza thanks to a £2,800 gift from Interpal.

Other speakers and panellists at the Westminster conference on August 22 include Pedro Charbel, from a group that calls for a boycott of Israel, and Dr Mohsen Saleh, who was thanked by Hamas leader Khaled Meshaal for organising an Islamist conference in 2012.

Also at the event – entitled Palestine and Latin America: Building Solidarity for National Rights – will be Andrew Murray, the chief of staff at Mr Corbyn’s union backers Unite.

Islington MP Mr Corbyn has a history of associating with terror groups. He caused outrage in 1984 when he invited Gerry Adams to the Commons a fortnight after the Brighton bombing.

More recently he has invited figures from Hamas and the Lebanese militant group Hezbollah to Parliament, describing them as his ‘friends’. He claimed the UK’s decision to label Hamas a terror group was a ‘historic mistake’.
