Britain's law and order chief says the government will publish lists of radical preachers and other extremists banned from entering the country.

Jacqui Smith told lawmakers Tuesday that identifying those refused entry to the country would help stop "those who foster, encourage or spread extremism."

Since 2005, around 230 people have been turned away by Britain's government, including radical Muslim clerics, neo-Nazis and radical animal-rights activists.

Among those who've been refused entry is Lebanon-based cleric Omar Bakri Mohammed. He is the former head of the now-disbanded group al-Muhajiroun, which gained notoriety for praising the Sept. 11 hijackers.
