Background: Public school and Oxford. Conservative MP for Louth, 1969-74. Deputy Chairman of the Tories, 1985-86.

If he had been an MP, he would have been forced to leave Parliament. Indeed, he felt he had to quit the Commons in 1974 after running up financial problems, although he had committed no offence. He does not speak or vote.

Lord Falconer of Thoroton Labour
Background: Public school- and Cambridge-educated barrister, aged 46. A QC since 1991.

Blair then gave him a peerage, and a sequence of Government posts, including a period running the Greenwich Dome. He has been Lord Chancellor since 2003.

Baroness Thatcher of Kesteven Conservative
Background: Now 81, she is the daughter of a grocer from Grantham.
Best known as: Maggie Thatcher, the longest serving prime minister of the 20th century. It is assumed that part of the reason why she left the Commons in 1992 and accepted a peerage was in order not to be like Sir Edward Heath, her predecessor, who stayed lurking in the Commons for many years. Her successor, Sir John Major, left the Commons but did not take a peerage, perhaps he did not want to see either of them ever again.

Lord Williamson of Horton Crossbencher
Background: Tonbridge School, then Oxford University.
Best known as: 'Convenor' of the crossbench group of peers. This is not the same being a party leader, because he does not try to tell the crossbenchers how to vote, but he keeps them up to date with parliamentary business and handles negotiations. The 72-year-old learnt this skill as a career diplomat and civil servant. He is a more assiduous attender at the Lords than other crossbenchers, who include quite a number of permanently absent or silent members.
