The Home Secretary may exclude from the UK any person where she judges that their presence here would not be conducive to the public good. A person so excluded will be refused a visa or permission to enter the UK should they make such an application. In August 2005 the then Home Secretary published a list of certain behaviours which, if engaged in, would normally lead to a person being excluded or deported from the UK. That list includes the expression of views that
“foster hatred which might lead to inter-community violence in the UK”.
Those who promote “race hate” fall within this provision.
