The insanity never ends.

(Daily Mail) — An Islamic extremist who is supposedly banned from Britain delivered a speech to a packed hall in the Midlands last night.

Raed Salah, who is accused of ‘virulent anti-semitism’, strolled through immigration checks at Heathrow Airport on Saturday, despite being excluded from the UK by the Home Secretary.

Last night, Raed Salah was giving a lecture organised by Islamist radicals to a large crowd in Leicester, and today he was due to speak at Westminster at the invitation of Left-wing Labour MPs.

Theresa May — determined to be tough on extremists — is furious with blundering UK Border Agency staff who allowed Salah into the country, and wants him removed as quickly as possible.

Yet, to the fury of Jewish groups, Salah was last night able to address a packed hall of 500 British Muslims in Leicester.

The cleric, leader of the northern branch of the Islamic Movement in Israel, also addressed an audience at Conway Hall, in London, on Monday evening.

Police were said to be trying to hunt him down, but he was not arrested at the event though the power is available to officers if his presence in Britain is considered not to be ‘conducive to the public good’.

Officials are now waiting to see if a hugely embarrassing appearance at Westminster, originally scheduled to take place alongside three Labour MPs, will go ahead today.

The MPs have been told by party managers they must not share a platform with a man who is banned from the UK. The event has been moved from the Commons to an undisclosed venue.
