Elizabeth Truss is Britain’s new Prime Minister.
The 47-year-old mother of two saw off the challenge by former Chancellor Rishi Sunak to take the keys to Number 10.
She garnered 81,326 party members’ votes to Mr Sunak’s 60,399.
The result was closer than people had expected.
Ms Truss said it was an “honour” to be the new leader of the “greatest political party on Earth”.
She added “I know that our beliefs resonate with the British people.
“I campaigned as a Conservative and I will govern as a Conservative
“I will deliver a bold plan to cut taxes and grow our economy.
‘We will deliver a great victory for the Conservative Party in 2024.”
Mr Sunak called for party unity.
He said: “The Conservatives are one family.
“It’s right we now unite behind the new PM, Liz Truss, as she steers the country through difficult times.”
Ms Truss, who was educated at the University of Oxford, will be appointed by The Queen.
The ceremony will take place for the first time at Balmoral Castle in Scotland.
Ms Truss takes over from Boris Johnson who resigned as the Tory party leader.
Mr Johnson tweeted: “Ms Truss ‘has the right plan to tackle the cost-of-living crisis, unite our party and continue the great work of uniting and levelling up our country.”
She is the third Conservative woman to become Prime Minister.
She follows in the steps of Margaret Thatcher and Theresa May.
Ms Truss is Britain’s 56th Prime Minister.
The Labour Party has never had a female leader.
