London: Theresa May on Wednesday became Britain's second woman prime minister after Margaret Thatcher, vowing to forge "a bold new positive role" for the UK in the world post-Brexit.
May, 59, took charge after she had her audience with Queen Elizabeth II at Buckingham Palace.
She spoke outside No. 10 Downing Street shortly after emerging from the palace, having paid the traditional visit to the British monarch to be invited to form a government.
"We face a time of great national change... As we leave the European Union we will forge a bold new positive world for ourselves, and we will make Britain a country that works for everyone of us.
"That will be the mission of the government I lead, and together we will build a better Britain," she said, in reference to Britain's recent vote to leave the European Union (EU) that brought her to power.
May becomes the second-ever woman Prime Minister of Britain, the 13th PM to be officially appointed by the Queen and?the 54th holder of the office of British prime minister since it was created in the 18th century.
May was accompanied by husband, Philip May, as she addressed the world's media waiting at Downing Street?since her predecessor David Cameron had departed just over an hour earlier.
"In David Cameron, I follow in the footsteps of a great, modern prime minister... He led a one-nation government and it is in that spirit I also plan to lead," she said in her first speech as PM, wearing a black and yellow coat and her trademark leopard print kitten-heel shoes.
A heavy workload already waiting for her in-tray after the Brexit vote.
She addressed the working classes directly, saying she would give them more control and put "social justice" at the heart of her government and pledged to stand up against "the privileged few" and fight "burning injustice".
"The government I lead will not be driven by the interests of the privileged few, but by yours. We will do everything we can to give you more control over your lives. When we take the big calls, we'll think not of the powerful, but you.
"When we pass new laws we'll listen not to the mighty, but to you. When it comes to taxes we'll prioritise not the wealthy but you.
"When it comes to opportunity we won't entrench the advantages of the fortunate few. We will do everything we can to help anybody, whatever your background, to go as far as your talents will take you."
May also made a reference to the Conservative party's complete name, which is the Conservative and Unionist Party, saying the word "unionist" was very important to her as it highlights the "precious, precious bond" between all parts of the United Kingdom - England, Scotland, Wales and Northern Ireland.
