LONDON (AFP) - The radical Muslim group Al-Muhajiroun will not back down from plans to hold a demonstration on Sunday in central London despite a ban imposed by the city authorities and their threat to sue the organisers.

"Al-Muhajiroun do not have permission to hold a rally on Trafalgar Square and they have not applied for permission," a spokesperson for the city authorities said. The city had sent a letter to the head of the group's British branch but had received no reply.

Up to 700 sympathisers are expected to attend the event, aimed at converting non-Muslims to the faith. There are fears that Britain's extreme right-wing right party, the BNP, might organise a rival demonstration in Trafalgar Square, a favourite haunt of tourists in London.

UPDATE: [3] The rally has been canceled after all -- or at least moved.
