The life and work of Sir David Frost, who died of a heart attack on board a cruise liner last year, will be commemorated in a memorial service at Westminster Abbey later today.
Sir Michael Parkinson, BBC director general Tony Hall and Joanna Lumley will be among those paying tribute to the broadcaster who died in August aged 74.
Prince Charles will join Sir David's widow, Lady Carina Fitzalan-Howard, in laying flowers at a memorial stone dedicated to the television star near Poets' Corner.
Known for his incisive interviews - above all with disgraced US president Richard Nixon - Sir David spent more than 50 years as a television star.
His award-winning interview style was considered non-aggressive, affable and effusive - but he had a talent for extracting intriguing information and revealing reactions from his subjects.
