Veteran broadcaster Sir David Frost has died at the age of 74 after a suspected heart attack while on board a cruise ship.
A family statement said he had been giving a speech aboard the Queen Elizabeth on Saturday night.
Sir David’s career spanned journalism, comedy writing and daytime television presenting, including The Frost Report.
Internationally, he will be remembered for his revealing interviews with former US President Richard Nixon.
A 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.”
The BBC’s Barney Jones, who edited his Breakfast with Frost programme on the BBC for more than 10 years, said: “David loved broadcasting, did it brilliantly for more than 50 years and was eagerly looking forward to a host of projects - including interviewing the prime minister next week - before his sudden and tragic death. We will all miss him enormously.”
Prime Minister David Cameron said: “Sir David was an extraordinary man, with charm, wit, talent, intelligence and warmth in equal measure.
“He made a huge impact on television and politics.”
Sir David joined broadcaster Al-Jazeera in 2006 when it launched its English-speaking service.
He married his second wife, Lady Carina Fitzalan-Howard, in 1983 and they had three sons.
He worked closely with a number of charities over the years, including Alzheimer’s Research Trust, the Motor Neurone Disease Association and health charity Wellbeing of Women.
