David Seidler, best known for writing the Oscar-winning film The King’s Speech, has died aged 86.

The London-born screenwriter, who had a stammer, brought the true story of how King George VI overcame his speech impediment to the big screen.

The 2010 film starred Colin Firth, who also won the best actor Bafta and Oscar for his depiction of the king.

Seidler was also behind the stage adaptation of the film, which opened in the West End in 2012.
