Excerpt:
One of the main speakers at this weekend's Palestine Expo event has previously delivered lectures in which he compared Jews to "fleas", described equality between the sexes as "absurd", and defended violent jihad as "part and parcel" of Islamic teaching.
Sheikh Ebrahim Bham, an Islamic preacher from South Africa, is booked to speak on both days of the controversial conference in Westminster, where he is listed as one of the "acclaimed" guests.
The Palestine Expo event, cleared to go ahead by the government following concerns over the organisers' links with terror group Hamas, is supported by leading trade unions including the National Union of Students, the National Union of Teachers and Unite the Union.
