The sorry state of ‘equality’ in UK universities

I have been on and equality & diversity committee for an Australian university trying to get Athena-Swan accreditation. We were recently successful in getting an exemption to the gender discrimination legislation, to hire three women-only lectures in maths. There had been no women staff for a while - now it is at 30%. We are unusual in that the Dean and several Heads of Departments are women of science. We even break the national trend by having several Aboriginal lecturers, and the national ARC (research council) has a special scheme for Indigenous researchers only. I am about to join a UK university that has at least received Athena-Swan accreditation, and has 30% women promoted in the last round, but I note the population of the town is 4.4% minorities and the university has been unable to recruit minority staff, as the VC admitted - about 30% here so I am not looking forward to the change.
