<P> At HM Treasury the chancellor is supported by a political team of four junior ministers and by permanent civil servants . The most important junior minister is the Chief Secretary to the Treasury, a member of the Cabinet, to whom the negotiations with other government departments on the details of government spending are delegated, followed by the Paymaster General, the Financial Secretary to the Treasury and the Economic Secretary to the Treasury . Two other officials are given the title of a Secretary to the Treasury, although neither is a government minister in the Treasury: the Parliamentary Secretary to the Treasury is the Government Chief Whip in the House of Commons; the Permanent Secretary to the Treasury is not a minister but the senior civil servant in the Treasury . </P> <P> The chancellor is obliged to be a member of the Privy Council, and thus is styled the Right Honourable (Rt . Hon .). Because the House of Lords is excluded from Finance Bills under the Parliament Acts, the office has since the early 20th century been effectively limited to members of the House of Commons . The chancellor holds the formerly independent office of Master of the Mint as a subsidiary office . </P> <P> The Chancellor's official residence, since 1828, is No. 11 Downing Street . In 1997, the then First and Second Lords, Tony Blair and Gordon Brown respectively, swapped apartments, as the Chancellor's apartment in No. 11 was bigger and thus better suited to the needs of Blair (who had children living with him, including one born during his tenure) than Brown who was at that stage unmarried . </P> <P> Dorneywood is the summer residence that is traditionally made available to the chancellor, though it is the prime minister who ultimately decides who may use it . Gordon Brown, on becoming chancellor in 1997, refused to use it and the house, which is set in 215 acres (87 ha) of parkland, was allocated to Deputy Prime Minister John Prescott . It reverted to the chancellor in 2007, then Alistair Darling . </P>
