'Sunset Boulevard' starring Nicole Scherzinger swept the board at this year's Olivier awards

Its technical team was also recognised with best lighting design for Jack Knowles, musical supervision going to Alan Williams and best sound design being handed to Adam Fisher.

Jamie said at the event Nicole had given a "performance for the ages" and said he expected the production to take Broadway by storm when it transfers to New York later this year.

'Succession' actress Sarah Snook, 36, took home best actress for the 26 roles she played in 'The Picture of Dorian Gray', which was her West End debut.

She said about learning her lines while breast-feeding her baby at night: "Why am I doing a 60,000-word monologue with an eight-month-old baby?"

James Graham's football drama 'Dear England' took home two awards - best new play and best actor in a supporting role for Will Close.

Will dedicated his award to "all the single mums in council houses" and said his mother's encouragement was the reason he continued in theatre.

Mark Gatiss, 57, picked up a best actor for his turn in 'The Motive and the Cue' - and he also slammed today's theatre industry for being closed off to ordinary actors.

He said "as a working-class man who went to comprehensive school, all the routes that took me here have virtually vanished".

'Operation Mincemeat' about a World War Two plot to dupe the Nazis took home best new musical, while Amy Trigg took home a best actress gong in a supporting role in a musical category for her performance as Agnes in 'The Little Big Things'.

Arlene Phillips, 80, won best choreography with James Cousins for 'Guys and Dolls' and there was a posthumous recognition for 'Drop the Dead Donkey' star Haydn Gwynne, who died aged 66 in October.
