New Conservative leader David Cameron last night named a unity Shadow Cabinet that included key supporters of his former rivals.

Theresa Villiers, an MP for only seven months, was a surprise addition in what was otherwise a reshuffle of the existing pack.

Ms Villiers, formerly a senior Tory MEP, was appointed Shadow Chief Treasury Secretary.

Andrew Mitchell and Chris Grayling, campaign managers for David Davis and Liam Fox, were among those who remained in the top team.

Mr Cameron said: "This is a very strong team that draws on all the best talents in the Conservative Party.

"I know that together we can address the challenges facing Britain today with energy and confidence so that at the next election we are in a position to take forward a Conservative agenda of hope, optimism and change."

However, there may be surprise at how little the line-up has altered from that appointed by predecessor Michael Howard.

Mr Cameron promised to use his leadership victory to transform the way the party looks and sounds. Despite this, the vast majority of faces around the table were there under Mr Howard.

The addition of Ms Villiers and Shadow Wales Secretary Cheryl Gillan doubles the number of women in the Shadow Cabinet. But Theresa May will be unhappy to be shunted from her culture and family brief to Shadow Commons Leader.

Hugo Swire, an Old Etonian like Mr Cameron, joins the top team as Shadow Culture Secretary.

The other new face is Shadow Scottish Secretary David Mundell, the only Tory elected north of the border.

Peter Ainsworth follows former leader William Hague, who on Wednesday was named Shadow Foreign Secretary, back into the top team.

Mr Ainsworth returns to the environment post he gave up to nurse his wife through cancer.

David Willetts, a Davis supporter, fills Mr Cameron's shoes as Shadow Education Secretary. Alan Duncan was promoted to the Shadow Trade Secretary brief that Mr Willetts held.
