The star of a new BBC show charting the lead up to World War One says television needs "more informative drama".

Tim Pigott-Smith plays beleaguered Prime Minister, Herbert Asquith, in 37 Days.

He told the Andrew Marr Show: "One of the functions of drama is to teach... I think people will learn a lot from this and for me this really justifies the licence fee".
