Hercule Poirot may soon have to be played only by a Belgian actor, David Suchet has suggested, as he warns the pendulum of political correctness can swing too much the other way.

Suchet, the British actor known for his portrayal of Agatha Christies detective, said there must be limits to the modern demands placed on actors to play parts only similar to themselves.

Speaking of his own career, which saw him black up to play Caliban in a 1978 stage production of The Tempest, he said it was right that the world had moved on but suggested the industry risked going too far.

The world has changed, he told the Mail on Sunday. It has to change. It's not my world. I'm trying to catch up with it.

But I think there are limits. How much do you change of a play - dialogue or character-wise - to suit political correctness?

I'm a character actor. I don't want who I can play to become small because of political correctness.
