David Cameron has said Sir David Frost was an "extraordinary" man who made a "huge impact" on television and politics.
– Prime minister David Cameron
My heart goes out to Carina and the family. 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. The Nixon interviews were among the great broadcast moments - but there were many other brilliant interviews. He could be - and certainly was with me - both a friend and a fearsome interviewer.
