The award has already proved its pedigree by spotting such meteors as Southwark Playhouse artistic director Thea Sharrock - whose Top Girls transferred from the BAC to the West End - and Mark Rosenblatt, whose prize-winning The Dybbuk has been succeeded by a series of fringe and West End productions that have maintained the buzz surrounding his name. Now this year's winner, Bijan Sheibani, takes on two of Pinter's most overtly political plays and makes an engaging case for their menacing humour and relevance in today's paranoid political climate.
