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.” Yahoo! News UK
