I want a Hungarian lesbian dwarf...

I thought it was illegal to advertise for a job in such a way as to make certain would-be applicants ineligible by virtue of their gender, race or other personal characteristics.  Well, if it is, it seems it doesn't apply to the BBC.  They are looking for a new host for their "One Show" programme, and have specified that they are looking for a male, over 30 from "an ethnically diverse background" (whatever the heck that means) and who has a regional accent - preferably northern.  Personally, I've little time for anti-discrimination legislation, but it exists, and surely this falls foul of it?
