After winning re-election, British Labour Party M.P. Johnnie Byrne faces a series of setbacks in his political career, as well as in his marriage, and must act wisely in order to save both.
Johnnie is frequently referred to as a back-bencher. Front-benchers, who sit on the first of the long benches in the House of Commons, are members of the Cabinet. Back-benchers are those who sit on any of the other benches; they are simply Members of Parliament and have no other position.
The on street interview that Finch's character gives to a news film crew has somewhat different wordage (clearly from another take, that would not have happened with a news crew) when seen broadcast later on a television in a pub.
