According to the BBC News site, here,


"Staff joining the BBC will be asked about their socio-economic background, as part of a bid to increase diversity at the corporation.
Candidates will be asked if they were entitled to free school meals, and if their parents attended university."

I would love one of the wonks who devise this sort of stuff to sit down and define "socio-economic background". A meaningless and therefore irrelevant phrase if ever I heard one. In my 25 years at the BBC I cannot recall that my ability to work with people was coloured by my upbringing or theirs.
