Celebs on the Farm, 10pm / 5Star, Channel 5

Prepare for two weeks of mud, sweat and tears as eight celebrities swap the glamour of the showbiz circuit for life on the farm in this new 10-part weeknight series. After turning up in an outfit more suitable for a film premiere than looking after livestock, glamour girl Charlotte Dawson is the first to come a cropper in her high heels, but she’s not the only one a country mile out of her comfort zone. This week’s first episode (showing on Channel 5 as well as 5Star) sees the wannabe farmers get to grips with life on Lunsford Farm on the Sussex coast, but how many of them will muck in when the going gets tough? Continues weeknights on 5Star. Ratings: *****

The origins of his talent become clear as he learns about his late maternal grandfather, whose football career was cut short. He also discovers his great-great-grandfather was killed by anthrax.
