Sir Robert Frost will be remembered for his satirical show "That Was The Week That Was", part of the 1960s "satire boom", as well as for his revealing interviews with former US president Richard Nixon.
"He is survived by his second wife, Carina Fitzalan-Howard, and three children. A family statement said:
"His family are devastated and ask for privacy at this difficult time. A family funeral will be held in the near future and details of a memorial service will be announced in due course."
Some of Sir Robert Frost's memorable quotes include:
"Love is staying up all night with a sick child - or a healthy adult."
"Don't aim for success if you want it; just do what you love and believe in, and it will come naturally."
"Having one child makes you a parent; having two you are a referee."
"Diplomacy, n. is the art of letting somebody else have your way."
"Over the last half century the television interview has given us some of TV's most heart-stopping and memorable moments. On the surface it is a simple format - two people sitting across from one another having a conversation. But underneath it is often a power struggle - a battle for the psychological advantage."
