SINGER-songwriter Diana Vickers is wowing audiences with her role in a West End play.

The 22-year-old former Blackburn Westholme School student has started a stint in ‘The Duck House’, a comedy about MPs’ expenses, which will run at the Vaudeville Theatre, in London.

The play has already been touring the UK, taking Diana, who is from Huncoat, to Guildford, Malvern, Nottingham and Cambridge.

The play is set in May 2009, when Gordon Brown’s government is in meltdown, and a General Election is a year away.

The action centres around Labour backbencher Robert Houston, who switches to the Conservatives to save his seat.

All is going well with his defection until the expenses scandal breaks.

As public fury mounts, Robert and his secretarial staff, aka wife Felicity, student son Seb, Russian housekeeper Ludmilla, and Seb’s girlfriend Holly, played by Diana, find themselves in big trouble.

Diana is starring alongside Ben Miller, best known as one half of comedy double act Armstrong and Miller.
