The British government on Wednesday released guidelines for barring foreigners the government believes inspire terrorism, as part of a broad crackdown on Islamist preachers after last month's deadly bombings in London.
"The terrorist threat facing the UK remains real and significant and it is right that the government and law enforcement agencies do everything possible to counter it," Interior Minister Charles Clarke was quoted as saying by Reuters.
"That includes tackling those who seek to foster hatred or promote terrorism, sending a strong message that they are not welcome in the UK."
Two waves of bomb attacks in London which killed 52 commuters in the capital last month prompted a series of new anti-terrorism measures and Prime Minister Tony Blair says the "rules of the game are changing".
He added that the list was 'indicative rather than exhaustive'.
"Individuals who seek to create fear, distrust and division in order to stir up terrorist activity will not be tolerated by the Government or by our communities," he was quoted as saying by the AFX.
The list covers any non-UK citizen whether in the UK or abroad who uses any means or medium to 'express views which foment, justify or glorify terrorist violence in furtherance of particular beliefs; seek to provoke others to terrorist acts; foment other serious criminal activity or seek to provoke others to serious criminal acts; or foster hatred which might lead to inter-community violence in the UK'.
