Sixteen people banned from entering the UK have been named by the Home Office.
Home Secretary Jacqui Smith said she decided to make public the names so others could better understand what sort of behaviour Britain was not prepared to tolerate.The list includes hate preachers, anti-gay protesters and a far-right US talk show host.
"I think it's important that people understand the sorts of values and sorts of standards that we have here, the fact that it's a privilege to come and the sort of things that mean you won't be welcome in this country," said Ms Smith.
"Coming to this country is a privilege. If you can't live by the rules that we live by, the standards and the values that we live by, we should exclude you from this country and, what's more, now we will make public those people that we have excluded.
"We are publishing the names of 16 of those that we have excluded since October. We are telling people who they are and why it is we don't want them in this country."
The list of the 16 "least wanted" includes radio talk show host Michael Savage, real name Michael Weiner.
"This is someone who has fallen into the category of fomenting hatred, of such extreme views and expressing them in such a way that it is actually likely to cause inter-community tension or even violence if that person were allowed into the country," said Ms Smith.
Also named are American Baptist pastor Fred Waldron Phelps Snr and his daughter Shirley Phelps-Roper, who have picketed the funerals of Aids victims and claimed the deaths of US soldiers are a punishment for US tolerance of homosexuality.
Hamas MP Yunis al-Astal, Jewish extremist Mike Guzovsky, former Ku Klux Klan grand wizard Stephen Donald Black and neo-Nazi Erich Gliebe are also on the list released.
Artur Ryno and Pavel Skachevsky, the former leaders of a violent Russian skinhead gang which committed 20 racially motivated murders, are also banned from coming to Britain. Both are currently in prison.
Making up the rest of the 16 are preachers Wadgy Abd el-Hamied Mohamed Ghoneim, Abdullah Qadri al-Ahdal, Safwat Hijazi and Amir Siddique, Muslim activist Abdul Ali Musa (previously Clarence Reams), murderer and Hezbollah terrorist Samir al-Quntar and Kashmiri terror group leader Nasr Javed.
