Muslic radical is not let in Britain

Omar Bakri Mohammed, a cleric who left the U.K. after saying he wouldn't tell police about fellow Muslims who were planning terrorist attacks, won't be allowed to return, the government said Friday.

Home Secretary Charles Clarke issued an order to revoke Bakri Mohammed's residency permit and “exclude him from the U.K. on the grounds that his presence is not conducive to the public good,” the Home Office said in a statement read by a spokeswoman in a telephone interview, Bloomberg says.

The cleric is being held by the Lebanese authorities in Beirut, but the UK did not request his arrest.

He was seized after a TV interview in which he said he would only return to Britain as a visitor but not as a persona non grata.

The preacher left Britain six days ago on what he described as a holiday to see his mother in Beirut.

Since the 1980s he has had indefinite leave to remain in the UK after gaining political asylum.

He is thought to have dual Syrian and Lebanese nationality.

The preacher has caused controversy by saying he would not report a potential bomber to the police and is currently being investigated by UK authorities, BBC reports.

His arrest on Thursday came as 10 foreign nationals, who the Home Office says pose a threat to national security, were detained in the UK, pending deportation.

U.K. Prime Minister Tony Blair has been under pressure to act against extremists after four British Muslim bombers killed themselves and 52 others in attacks on London's transportation system on July 7.
