Incitement to Racial Hatred - Part III Public Order Act 1986
The Act defines “racial hatred” as hatred against a group of persons defined by reference to colour, race, nationality (including citizenship) or ethnic or national origins).
For an offence to be committed under any of these sections of the Public Order Act 1986, there has to be one of the acts described therein: it has to be "threatening, abusive or insulting", and it has to be intended to or likely in all the circumstances to stir up racial hatred.
