4) The Lord Heseltine – £278 Million

Lord Heseltine is infamous for his role in the downfall of Margaret Thatcher from her role as Conservative Party leader and Prime Minister. He was also a respected and maverick member of her cabinet, until his resignation in 1986, and that of her successor John Major.

A former university friend of Heseltine tells an anecdote that he’d once planned out his career on the back of an envelope. It read millionaire at 25, cabinet minister at 35, party leader at 45 and Prime Minister at 55. Whilst Heseltine never achieved the latter two he did the former, becoming a millionaire before his entry into parliament due to his successful publisher, Haymarket. After his retirement from the Commons in 2001 he returned to the company to fulfil a more hands-on role alongside his place in the House of Lords.

3) Zac Goldsmith (MP) – £284 Million

Much of Goldsmith’s wealth is inherited from his father, Sir James Goldsmith, who left £1.2 billion to his extended family following his death. His father was also involved in politics having founded the Referendum Party during the 1990’s, a single issue party demanding a referendum on Britain’s EU membership.

Goldsmith junior was first elected to the Commons in 2010 in the Richmond Park constituency after being placed on David Cameron’s controversial A-list before the election. He has been tipped to stand for the Conservative Party in the 2016 London Mayoral Election, whether he decides to stand is another matter.
