Nominations have been announced for the 2006 Laurence Olivier Awards, the UK's most prestigious stage and theatre awards. Dubbed 'London's equivalent of the Tony Awards', the 30th annual Laurence Oliver Awards will be announced in a ceremony at the London Hilton on Sunday, 26th February. The Hilton UK & Ireland hotel chain are sponsors of the awards. Awards will be presented in over 20 categories including Best Actor, Best Actress, Best New Musical and Outstanding Musical Production as well as fields such as Outstanding Achievement in an Affiliate Theatre. The awards are organised by the Society of London Theatre, the trade association which represents the producers, theatre owners and managers of the major commercial and grant-aided theatres in central London. Established in 1976 as the Society of West End Theatre Awards, the awards were renamed in 1984 in honour of legendary British actor Laurence Olivier.
