Revered British broadcaster Sir David Frost has died. The 74 year old passed away after suffering a suspected heart attack while on vacation aboard the Queen Elizabeth cruise ship on Saturday night (31Aug13). The boat was en route from Southampton, England to Lisbon, Portugal. A statement from his spokesperson reads, "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 U.K.'s Prime Minister David Cameron has led the tributes to the legendary newsman, stating, "My heart goes out to David Frost's family. He could be - and certainly was with me - both a friend and a fearsome interviewer." Meanwhile, a number of celebrities have taken to Twitter to remember Frost, with actor Russell Crowe writing, "RIP David Frost. Met the man for the first time at the Ashes test at Lord's. What a legend." Close friend Stephen Fry adds, "Oh heavens, David Frost dead? No!! I only spoke to him on Friday and he sounded so well. Excited about a house move, full of plans... how sad." Another family friend, actress/author Joan Collins, adds, "My heart goes out to Carina, widow of David Frost - he was a brilliant broadcaster and a true life enhancer." Frost, a noted interviewer and journalist, launched his media career in the 1960s, but actually started out in comedy, fronting satirical shows That Was The Week That Was and The Frost Report. He moved into serious news with The Frost Programme, in which he interviewed a string of powerful people. In 1977 he became internationally famous for his revealing and candid interview with former U.S. President Richard Nixon following the Watergate scandal. The interview inspired the 2008 film Frost/Nixon, in which Michael Sheen played the broadcaster, while Frank Langella portrayed Nixon. He was beloved in Britain for his longrunning panel show Through the Keyhole, which ran from 1987 to 2008. He also fronted Sunday news programme Breakfast with Frost for 12 years and most recently worked on a weekly show for Al Jazeera English. He is survived by his wife Lady Carina Fitzalan-Howard and their three sons.
