Gill Sans  Suggested by gonfer00 

I don't know why this font has not been marked as identified. It's official that BBC uses Gill Sans (https://en.wikipedia.org/wiki/Gill_Sans https://www.bbc.co.uk/commissioning/tv/production/articles/credits-branding-trademarks ) although in BBC Sports they have started to use Reith (https://www.bbc.co.uk/gel/articles/introducing-bbc-reith )
