Start as a new MP. Make your way through selection, backbench years, junior government, Cabinet, and finally the leadership. Every choice links to a real MP's career decision.
Choose your party. Nine career stages. Four meters: Party Standing, Media Profile, Political Judgement, Parliamentary Network. All start low - you are new. Build them high enough and you will reach Number 10. Get too many calls wrong and you will end your career as a footnote.
