Sheikh Omar Bakri Mohammed: Defiant

His organisation was stopped from holding a meeting in Cardiff in the wake of the 11 September terrorist attacks in the US.

The Sheikh was due to speak at Shah Jahal Mosque this weekend, but mosque trustee Mohammed Ahad Chowdury said the invitation was unexpected and unwelcome.

Sheikh Mohammed is understood to have regularly visited Cardiff to meet with students and has pledged that the banned visit this month will not put him off returning again.

We'll find out who gave the permission and we're going to take action against the person

Mr Chowdhury told BBC Wales: "At the moment, we don't know where they (Al Muhajiroun ) got the permission from.

"We don't allow any sort of extremists: ourselves we are not extremist and there's no way can we allow those sort of meetings in our mosques."

"We are going to find out who are those people. As far as I know the majority of people in the community don't like extremists.

Mr Chowdhury added: "Whoever gave the permission it is totally wrong.

"We'll find out who gave the permission and we're going to take action against the person who gave permission to those boys or extremists."

Sheikh Mohammed said he could not understand why the ban had been imposed.
