"In the Cold War John le Carre was writing up a storm about the subject of the intelligence services, obviously he's the greatest writer on the subject - but there's nothing contemporary," he added.
Sir David received Oscar nominations for both The Hours in 2002 and The Reader in 2008.
His work often uses political material which can prompt readers to look for a message but Sir David insists that he does not write agitprop, and that his purpose isn't to try and change the system.

"I'm looking for metaphors, I'm interested in art - but I happen to use as my materials things from contemporary society."
"If I wanted to effect political change - I wouldn't choose the theatre as the most efficient way of doing it."
When asked if topical events like the recent riots in England would inspire his work, he replied: "Artists don't choose their subject matter - it chooses them. My opinions have nothing to do with my art."
One of his plays, Stuff Happens (which premiered in 2004), traces the origins of the Iraq war, puts it in perspective and analyses American politics.
"I feel that the world is changing so quickly in the 21st century that I'm almost having to resort to documentary because I've got no time to do some of the deeper processes of fiction."
Sir David said the premise of Page Eight was based on "informed guess work". Much of his political writing combines documentary realism with imaginative reconstruction of the arguments behind the publicly known facts.

"In Stuff Happens, two thirds of what went on in the diplomatic process leading up to the invasion of Iraq happened behind closed doors - nobody knows what happened.
"When Tony Blair and George Bush went for a walk in the woods in Crawford, Texas, they didn't even take their assistants with them, which made their assistants extremely nervous - nobody knows what they said."
"I wrote that scene as a fictional encounter, I invented that scene, and people will never know whether it was true or not - and that's exactly the same as what Shakespeare and Schiller did."
According to Sir David the accuracy of the final encounter has been described as "very good guess work" by people who were party to those events.
He has written a new play, South Downs, which is currently in rehearsal, and is partly based upon Sir David's own experiences as a schoolboy at Lancing College, in Sussex.
"It's about that moment at which a boy of 13 begins to realise who he is."
"There's a terrible moment in your life when you realise, as one of the characters says, you're condemned to live your whole life in the company of someone you don't like very much - namely yourself."
