Member of Parliament (UK)
The professional career of a Member of Parliament normally begins when he or she finds a parliamentary constituency in which the selection committee of the local branch of a political party is willing to adopt him or her as their prospective parliamentary candidate. After being elected to the House of Commons, parliamentary loyalties are acquired, but constituency loyalties cannot be set aside.
Getting elected
In principle, anyone can become a Member of Parliament provided that he or she is aged 18 or over, a citizen of the United Kingdom, the Commonwealth or the Republic of Ireland, and not a disqualified person (such as a government employee, or a member of the House of Lords). All that is necessary to stand for election is a nomination paper signed by ten voters, and a £500 deposit. Membership of a political party is not necessary, but it is almost impossible to mount an effective election campaign without party support. Selection as a party candidate is a two-stage process because the central organisations of United Kingdom political parties maintain lists of people who have passed their vetting procedures, from which local party committees are free to choose their prospective parliamentary candidates
