Dublin-born actor Andrew Scott has won the Best Actor Olivier for his role as Garry Essendine in Present Laughter at the Old Vic theatre in London.
The Olivier Awards are presented annually for outstanding achievements in theatre in the UK.
Scott faced tough competition from Toby Jones for his part in Uncle Vanya, James McEvoy for his role in Cyrano De Bergerac, and Death Of A Salesman star Wendell Pierce.
Last year, Scott won an Evening Standard Theatre Award for the same role at a different theatre.

Earlier this month Scott was awarded the Best Actor in a Drama Series at the IFTA Awards for his guest-starring role in hit TV show Black Mirror.
In 2012 he won the Best Supporting Actor BAFTA for his role in Sherlock. He was also awarded a Critics' Choice award for his portrayal of the 'Hot Priest' in comedy Fleabag at the start of this year.
Meanwhile, Armagh-born Colin Morgan, best known for playing the titular role in BBC TV series Merlin from 2008 to 2012 missed out on Best Supporting Actor Award for his role in the play All My Sons.
Elsewhere, Mam by Teach Damhsa, led by Michael Keegan-Dolan, were nominated in the category of Best New Dance Production which was won by Ingoma by Mthuthuzeli November for Ballet Black.
Most theatres remain closed in the UK due to the coronavirus pandemic, as a result, the Olivier Awards are not expected to take place again until 2022.
