The play about a fictionalised version of the Bullingdon Club, which originally starred Kit Harington and James Norton, will return to the London stage with an all-female cast.
Posh, about an Oxford student dining society known as The Riot Club, was first staged at the Royal Court in 2010.
It starred Kit, who would go on to find fame in Game Of Thrones, and James, who enjoyed a breakout role in Happy Valley.
The show later transferred to the West End with some cast changes and was turned into a film, called The Riot Club, starring Douglas Booth, Max Irons and Sam Claflin.
Now Laura Wade's play based on the famous dining club of which David Cameron, George Osborne and Boris Johnson were members, will be staged by a company of all-female actors.
It centres on the elite society's dinner in the private dining room of a gastro pub, with the members intent on restoring their perceived right to rule.
The new production will be directed by Cressida Carre, with the cast yet to be announced.
It will run at the Pleasance Theatre in Islington from March 29 to April 22 with press night on April 3.
