The British producer of The Apprentice is coming under increasing pressure to release footage from the Donald Trump-led reality television show, amid growing suggestions that there is a trove of damaging material being held back.

Mr Trump's presidential campaign has been rocked by leaked footage from an episode of Access Hollywood, in which he brags about sexually assaulting women.

Critics of the Republican nominee are eager for the release of unaired recordings from The Apprentice, a show which Mr Trump lead from its creation in 2004 until 2015.

The show is produced by Mark Burnett, a 56-year-old London-born executive, who is now president of MGM Television.

He is described as a reality television titan, having created Survivor, The Voice and Shark Tank - the US version of Dragon's Den.
