Free speech for racists?

Apparently the representatives of colonial settler states based on ethnic cleansing and apartheid laws are entitled to free speech in UK universities. In a Guardian. report that looks like it was drafted for approval by the so-called Union of Jewish Students, and misleadingly headlined "College tells students to reverse Israeli ban", the principal of SOAS invoked "freedom of speech laws" to overturn a SOAS students' union ban on Roey Gilad, political counsel from the Israeli embassy. Roey Gilad said:

This goes against freedom of speech which should be everywhere but in universities in particular. It prevents someone presenting his agenda, and someone who represents a legitimate state. I didn't expect this in the UK, let alone at a university.

Making a nonsense of the SOAS principal's appeasement of racists the article ends with an in-brief piece as follows:

Students at Prince William's university yesterday withdrew their invitation to the leader of the British National Party to speak at a debate after a protest. Nick Griffin had been invited by members of St Andrews University Debating Society to take part in a debate on the shortcomings of multiculturalism.

I wonder if "freedom of speech laws" will be invoked there as well.
