David Dashwood is surprisingly elected as Conservative MP at a by-election in marginal Westling-on-Sea. Flushed with success, he is set to go to Westminster with his ideals intact.

David Dashwood makes his first TV appearance and doesn't realise that he has been set up by the Labour Whip. Terry Dunning, the Tory Whip, is not amused.

David Dashwood is due to make his maiden speech and he's determined to make his mark, despite the attempts of Terry Dunning to restrain him. Then Graham Keegan receives a worrying phone call.

After Dashwood has made his provocative maiden speech and the knives are out for him... within his own party. Labour whip Graham Keegan has his own problems, and is fighting for his political life.

Although David is pleasing his constituents, his wife Laura is giving the Westling constituency chairman serious cause for concern.

Antonia Courtney is giving Terry Dunning difficulties. Will his threat to deport her have the desired effect?

David threatens to force a defeat on the Government, so Terry enlists the help of Fleur to manoeuvre him into an uncompromising position. Will blackmail work on the rebel?

A break-in at the whip's office gives Terry Dunning a major headache, and Fleur gets taken in for questioning.

It's the night of the crucial vote and Dashwood is determined to vote with the opposition - can he bring down the government?
