Full Cast Set for World Premiere of DEAD SHEEP at Park Theatre

The true story of how Mrs. Thatcher, the most divisive Prime Minister of modern times, was brought down by her one time friend and political soul mate.

It is 1989 and a seemingly invincible Prime Minister has sacked Geoffrey Howe, her Foreign Secretary. She apparently had nothing to fear from him: his speaking skills had, famously, been compared to those of a dead sheep. But inspired by his wife Elspeth - whose relationship with Thatcher was notoriously frosty - Howe overcame his limitations to destroy Mrs Thatcher with one of the great political speeches.

The staging of Dead Sheep, a drama tinged with tragedy and comedy, coincides with the 25th anniversary of Howe's assassination and its themes - loyalty, love, political morality and Britishness - are as relevant today as they were a quarter of a century ago.
