In February 2013 it transferred to the larger Olivier Theatre where it continued to play with much critical acclaim to packed houses until May 2013.
The action takes place in the period in British parliamentary history between the February 1974 general election and the 1979 vote of no confidence in the government of James Callaghan.
Although the play is based on real events, it is neither a documentary nor a biography, but a fictionalised account of a turbulent period in British politics.
These years involved very tense periods in Parliament, with the Labour and Conservative whips working hard to defend and remove the Government respectively.
This situation got more difficult between October 1974 and March 1979 as the Labour government lost MPs in by-elections and defections to other parties.
