In 1986, the British television production company Granada Television created a near-full size replica of the post-1950 House of Commons debating chamber at its studios in Manchester for use in its adaptation of the Jeffrey Archer novel "First Among Equals". The set was highly convincing, and was retained after the production—since then, it has been used in nearly every British film and television production that has featured scenes set in the chamber. From 1988 until 1999 it was also one of the prominent attractions on the Granada Studios Tour, where visitors could watch actors performing mock political debates on the set. The major difference between the studio set and the real House of Commons Chamber is that the studio set has just four rows of seats on either side whereas the real Chamber has five.
