  • Special Branch officers are said to have feared he was trying to undermine Parliamentary democracy

The Labour leader was monitored for two decades because he was ‘deemed to be subversive’ according to a former Special Branch officer.

Jeremy Corbyn’s file was kept open by six commanders of the branch over the course of 20 years amid fears he was attempting to undermine democracy.

The Special Branch defines someone as subversive if their activities ‘intended to undermine or overthrow parliamentary democracy by political, industrial or violent means’.

Corbyn, and his shadow home secretary, both had files open at the same time under the ‘undermine’ category, the source told the Daily Telegraph

The Labour leader’s file was not linked to his alleged sympathies with Irish republicans, the source confirmed, but may have been connected to a speech he gave at a rally attended by the Al Muhajiroun, some of whom were dressed as suicide bombers.

He addressed an anti-Israel protest in May 2002 where Islamists from Al Muhajiroun chanted about their support for Osama Bin Laden and shouted slogans calling for Israelis to be gassed. Two were dressed in mock suicide bomber outfits. 

The Mail also revealed yesterday that he and his shadow chancellor John McDonnell both voted against the counter-terrorism law used to ban Al Muhajiroun and criminalise its members and leaders.

Details of the demonstration were found on the communist Weekly Worker website. It described the ‘ultra- reactionaries’ of Al Muhajiroun chanting ‘Skud, Skud Israel’ and ‘Gas, gas Tel Aviv’ , along with declarations of support for Al Qaeda.

Those in the ‘overthrow’ category would be arrested immediately. 

According to the source, files cannot be held ‘randomly’ and the commander has to have evidence to support the file remaining open.

The source told the paper: ‘Every single commander would have had to agree with that or the file would have been destroyed.’
