The boss of the BBC’s commercial arm has resisted calls to sell its stake in UKTV, the broadcaster behind the Dave channel, despite the opportunity for a GBP500m windfall to help cover funding gaps. Tim Davie, the chief executive of BBC Worldwide, said licence fee payers would be best served by a continued 50% stake in UKTV, which also runs Gold and Watch, as part of a 10-strong portfolio of digital channels. Scripps, a US media company owns the other 50pc, has made repeated approaches to buy out BBC Worldwide.
