New Conservative leader David Cameron today brought one of his predecessors William Hague back to the Tory frontbenches as shadow foreign secretary.

Defeated leadership rival Liam Fox was made shadow defence secretary, while David Davis stays as shadow home secretary, said a spokesman for the Conservative Party.

Mr Cameron's right-hand man George Osborne remains shadow chancellor, as expected, and Francis Maude stays on as party chairman while Oliver Letwin becomes director of policy.

Lord Strathclyde remains the Conservatives' Leader in the House of Lords.

The announcements follow Mr Cameron's first appearance as leader at Prime Minister's Questions in the Commons, where MPs got their first glimpse of his promised non-confrontational style less than 24 hours after his election victory.

True to his promise to do away with ''Punch and Judy politics'', the new Tory leader avoided the finger-pointing and raised voices usually seen in the weekly Commons clash in favour of a calm, measured tone.

And he surprised many MPs by offering Tony Blair the support of the Conservatives in pushing through his school reforms, which are bitterly opposed by many Labour backbenchers.

But the 39-year-old new boy also launched a few jibes at the 52-year-old Prime Minister, accusing him of being ''stuck in the past'', and telling MPs: ''He was the future once.''

Mr Cameron later launched a new Social Justice Policy Group, chaired by former leader Iain Duncan Smith, to look at the problems faced in the inner cities, including drugs, crime and family breakdown.

In his first full speech since his victory, Mr Cameron said he was ''deeply committed to social action for social justice''.

Speaking during a visit to a community centre in east London, he added: ''In the end, the test for our policies will not be how they affect the better-off, but how they help the worst-off in our country - empowering them to climb the ladder from poverty to wealth.''
