The new Sky Documentaries channel will feature a mix of programming from HBO, Showtime and Hulu alongside Sky originals, with launch programming including Hillary Clinton profile Hillary, gaming scam exposé McMillions and Muhammad Ali biography Ali Vs Cavett.

Sky Nature, meanwhile, will showcase natural history programming such as Wild Animal Babies, the David Attenborough collection and exclusive shows from specialist network Love Nature.
