US talk show host Michael Savage has said he was "shocked and angered" at being placed on a list of people banned from entering the UK.

The Conservative political commentator whose real name is Michael Alan Weiner, is one of 22 people barred for fostering extremism or hate.

He told his radio audience that he was intending to sue British Home Secretary Jacqui Smith, who he described as the "lunatic ... Home Secretary of England".

Speaking exclusively to the BBC Mr Savage said he would drop the threat if he received an apology.
