Extremists barred from entering the UK will be named and shamed under a tough new stance against so-called "preachers of hate" to be announced by the Government.
Home Secretary Jacqui Smith is to outline plans to publish lists of some individuals prevented from entering - including radical clerics and other extremists such as neo-Nazis.
Their names will also be shared with other countries.
A total of 230 people have been barred since 2005 but their identities have only become known when they have publicly complained about the decision against them.
An official said earlier this week that the new measures were aimed at "preventing anyone who will stir up tensions in the UK from entering the country".
"We have not named them in the past but now, when it was in the public interest, we will," the official added.
A Home Office spokesman said a written ministerial statement would be issued later on Tuesday.
"It's about excluding people for whom it is not in the public interest to come into this country." he said.
Radical Muslim cleric Omar Bakri Mohammed was banned from the UK in the wake of the 7/7 terror attacks in London in 2005.
