Actor Simon Callow has helped commemorate an influential theatrical agent by unveiling a blue plaque.

Peggy Ramsay nurtured some of Britain’s best acting talent and was one of the country's best known agents during the second half of the 20th Century.

Yesterday Mr Callow, star of hit film Four Weddings and a Funeral, unveiled a blue plaque at Peggy’s former home in Kensington Place, Brighton.

Peggy, who was played by Vanessa Redgrave in the film Prick Up Your Ears about Joe Orton, also nurtured some of the best-known British stage writers.

Among her clients, which included Orton, were Alan Ayckbourne, Robert Bolt, David Hare, Stephen Poliakoff and JB Priestley.

Mr Callow has written a book about his own relationship with Peggy, who was born in 1908 and died in 1991, called Love Is Where it Falls.
