Fay Weldon wasn't born in England, she was born in New Zealand in 1931 and moved to England as a teenager.
Go to work
Fay once worked in advertising and she is often credited for coining the slogan Go To Work On An Egg, a claim she refutes.
Famous for her feminist novels, Fay Weldon also adapted Pride and Prejudice for the BBC and wrote the series Big Women, as well as several episodes of Upstairs, Downstairs.
Fay was awarded a CBE in 2001. About the honour, Fay said: "One feels very flattered and honoured and it is nice to be acknowledged. But as an author you do all sorts of unseen work as well.
"I see this as an acknowledgement of that and that is how it should be. A lot of writers do this, because as soon as you get any public profile people ask you and you would have to be a very hard hearted person to say no."
Patricia Hodge has some hidden talents - she plays the piano and guitar, has a mezzo-soprano singing voice and has been trained in ballet and tap dancing.

Cloning Patricia Hodge
Another of Fay Weldon's novels adapted for television was The Cloning of Joanna May, which also starred Patricia Hodge. In the 1992 drama, Joanna May discovers her ex-husband has made three copies of her.
