He replaces Philip Hammond, who becomes chancellor. Ex-Energy Secretary Amber Rudd is home secretary and Eurosceptic David Davis is the Brexit secretary.

Ex-chancellor George Osborne was fired, the BBC's Laura Kuenssberg said.

On arriving at Downing Street, Mrs May vowed to lead a government that works for all, not just the "privileged few".

The UK's second female prime minister promised to give people who were "just managing" and "working around the clock" more control over their lives.

Mr Cameron will face his last Prime Minister's Questions in the Commons, before heading to Buckingham Palace to tender his resignation to the Queen.

He told the Daily Telegraph: "As I leave today, I hope that people will see a stronger country. It has been a privilege to serve the country I love."

After taking office, Mrs May will set about naming her own frontbench team.

Home Secretary Theresa May, the U.K.'s interior minister, told an audience at the Conservative Party conference that Britain should tighten control of its borders, admitting vulnerable refugees but keeping out those who simply want a better life.

She said other European countries should also toughen up their border controls, arguing that in the last few years more people had applied for asylum in the EU from Balkan countries — which have not seen war for years — than from war-torn Syria.

The One Direction band member is thinking about starting a career in acting, a source tells E! News exclusively. "Harry is being offered acting stuff, but he hasn't accepted anything yet," the source says.

"He is not openly looking for stuff either but is open to offers."

But the British heartthrob isn't going to accept just anything that comes his way just because it's offered. Harry is looking to appear on the silver screen only if it's a part that feels right. "If he does expand into that field," the source adds, "he wants to make sure it is the right role."

This is a new joint police command to target human traffickers and 10 million euros ($11.2 million) in new British government money to help asylum seekers and send others back home.

The measures are aimed at overcoming diplomatic and economic tensions around the French port of Calais, a flashpoint in a European summer marked by unusually large waves of migrants.

The statement represents his most direct signal to date that he will seek to expand his country's role in supporting the United States and its allies.

In remarks made to NBC News' "Meet the Press," Cameron said Britain must do more fight the group, also known as ISIL. The remarks, which follow a commitment to meet NATO targets on military spending, make plain that Britain now sees the group as an explicit threat to national security.

The announcement follows attacks in Tunisia, France and Kuwait on Friday. At least eight Britons were among the 39 people, mostly tourists, who were killed in the gun attack at Tunisian beach resort Sousse.

The Sun newspaper said police foiled an attack on a London military parade Saturday after an undercover reporter who obtained details on the plot alerted counter-terrorism officials. The paper said that an IS cell leader instructed the Sun's investigative reporter, who was posing as an aspiring militant, to target the parade.
