Irish actor Aidan Turner has scooped a best actor theatre award for his role in Martin McDonagh's acclaimed play The Lieutenant Of Inishmore.

The Poldark star made his West End debut in the leading role of Mad Padraic, a member of the Irish National Liberation Army, in the play that has been described as "a brilliant satire on terrorism" and an observation of "violence in contemporary culture."

Turner previously joked that the role was "the furthest I can get from Ross Poldark that I can possibly imagine".

Turner beat competition from Sherlock star Mark Gatiss, who was nominated for his turn in The Madness Of George III, to win Best Actor In A Play at the WhatsOnStage Awards, which are voted for by theatre goers.

Hamilton dominated the ceremony with five wins, including Best Actor In A Musical for Jamael Westman, who plays Alexander Hamilton in the Victoria Palace Theatre production.

The WhatsOnStage Awards ceremony took place at the Prince of Wales Theatre in London on Sunday March 3.
