Sir David Frost has died of a heart attack, at the age of 74, it was announced on Sunday.

Frost was born in 1939, and came to fame as a satirist in the 1960s, hosting the popular weekly comedy show That Was the Week That Was (known as TW3).

He also presented Breakfast with Frost, which ran until 2005 and featured interviews with politicians and news-makers.

Most recently, he worked for Al Jazeera, as the presenter of Frost Over the World.
