Page 55 of the BBC Annual Report and Accounts 2016/17 contains a table showing how many people the BBC employs in different parts of the UK. I have summarised the results for London and Scotland below.
|Location||% of UK Population||% of UK PSB Staff (equivalent full time)|
London’s population is only 60% greater that Scotland’s but the BBC employs 570% more Londoners that Scots.
Also remember that most, if not all, of these London employees will be paid the London weighting subsidy which comes out of the BBC tax.
