Midland Conservatives have welcomed the election of David Cameron as their party's fourth leader since Labour came to power in 1997.
Mr Cameron promised radical change for the Conservative Party after trouncing his rival David Davis by a margin of more than two to one, gathering 134,446 votes to 64,398.
After Mr Cameron's triumph was announced by Sir Michael Spicer ( Worcestershire West), chairman of the Tory MPs' backbench 1922 Committee, the 39-year-old former shadow Education Secretary made plain his desire to end Labour's grip on power.
Speaking without notes, he told cheering supporters: "I said when I launched my campaign that we needed to change in order to win.
"Now that I've won we will change. We will change the way we look. Nine out of ten Conservative MPs, like me, are white men.
"We need to change the scandalous under representation of women in the Conservative Party and we'll do that.
"We need to change the way we feel. No more grumbling about modern Britain. I love this country as it is, not as it was, and I believe our best days lie ahead.
"We need to change the way we think. It's not enough just to talk about tackling problems in our inner cites, we have to have all of the right ideas for turning those communities around.
"And we need to change, and we will change, the way we behave."
Former miner Patrick McLoughlin was named Tory chief whip - David Cameron's first appointment as leader.
He will announce the rest of his shadow cabinet today.
Mr Cameron, who launched the national phase of his leadership campaign in Birmingham, is expected to focus on attempts to win back seats in inner-city areas such as the West Midlands conurbation.
Last night city MP Andrew Mitchell (Con Sutton Coldfield), who was David Davis's campaign manager: "It has been a good-humoured contest and now the party will unite behind the winner."
Julie Kirkbride ( Con Bromsgrove) said: "I think he will attract people who haven't been our natural supporters in the last decade, particularly women and young people, and those are the groups we need to win back."
Philip Dunne (Con Ludlow) said: "I'm delighted. During the leadership campaign, I sent out a newsletter asking my constituents who the Conservatives should choose as leader and David Cameron was the favourite by six to one."
Michael Fabricant (Con Lichfield) said: "His agenda will change the direction of the Conservative Party as it looks towards the future rather than dwelling in the past."
And Peter Luff (Con Mid Worcestershire) said: "We face really tough challenges now, but we have a young and attractive leader and I am very optimistic."
Yesterday he promised Mr Davis would be a "a vital part of the team in the future".
Andrew Mitchell, the shadow International Development Secretary, and Caroline Spelman (Con Meriden), shadow Local Government Secretary, could also continue to play key roles.
The new Tory leader will face his first test today when he clashes with Tony Blair at Prime Minister's Question Time.
In a show of unity, defeated candidate Mr Davis hailed Mr Cameron as the new leader of the party and " the next Conservative Prime Minister".
Labour was contemptuous, fielding its former General Election co-ordinator Fraser Kemp to say: "David Cameron is a Conservative and stands for Conservative values.
"He has always chosen public spending cuts over investment in public services and opposed policies such as the New Deal and tax credits."
