British Prime Minister Rishi Sunak brought back former leader David Cameron as foreign minister on Monday in a reshuffle triggered by his firing of interior minister Suella Braverman after her criticism of police threatened his authority.

It was the latest reset for a prime minister whose party is badly lagging the Labour Party before an election expected next year. The return of Cameron suggested Sunak wanted to bring in a more centrist, experienced hand rather than appease the populist right of his party which supported Braverman.

It also reawakens divisive debate over Brexit: Cameron held the referendum on European Union membership in 2016 and was hated by many on the right of the party after he campaigned to remain. He quit hours after Britain voted to leave.

The ministerial reshuffle followed growing criticism of Braverman from opposition lawmakers and members of the governing Conservative Party, enabling Sunak to bring in allies and remove ministers he felt were not performing.

His hand was forced when the ever-controversial Braverman defied him last week in an unauthorised article accusing police of “double standards” at protests, suggesting they were tough on right-wing demonstrators, but easy on pro-Palestinian marchers.

The opposition Labour Party said that inflamed tensions between a pro-Palestinian demonstration and a far-right counter protest on Saturday, when nearly 150 people were arrested.

While her removal was not a surprise, it was the appointment of Cameron which caused shock in the party, welcomed by more centrist lawmakers but loathed by some on the right who described it as the ultimate “Brexit surrender”.

Cameron said he was glad to take on his new role at a time of global change: “It has rarely been more important for this country to stand by our allies, strengthen our partnerships and make sure our voice is heard”.

“Though I may have disagreed with some individual decisions, it is clear to me that Rishi Sunak is a strong and capable prime minister, who is showing exemplary leadership at a difficult time,” he wrote on X, formerly Twitter.

Cameron has been out of politics since 2016 and will be able to return to government via an appointment to the House of Lords upper house of parliament.

Brexit returns

Lawmakers in the centrist wing of the party said Cameron’s appointment would bring international experience, and send a wider message to the country.

“It’s a sign to the Tory blue wall and moderate voters, we aren’t heading to the right,” one Conservative lawmaker said, using a phrase that is used to describe traditional Conservative-supporting areas in the south of England.

Some lawmakers had feared that Braverman was determined to remake the Conservatives as the “nasty party” with her hardline focus on immigration and social issues, a moniker former Prime Minister Theresa May used in 2002 to try to persuade the party to shed its reputation of being uncaring.

But Cameron’s return compounded the anger felt by some on the right after her sacking. They backed her stance on protests and predicted she would remain a vocal force.

Some Brexit supporters also said Cameron’s role in the Brexit vote meant the so-called “remain” wing of the party had taken over.

James Cleverly, previously foreign minister, was appointed to replace Braverman. He is seen as a safe pair of hands and said his new role was “to keep people in this country safe”.

His first challenge will come on Wednesday when the Supreme Court rules on whether asylum seekers can be deported to Rwanda. A defeat in the key policy would lead some lawmakers to amplify calls for Britain to quit the European Convention on Human Rights.

With Braverman sidelined, her attentions might focus on preparing for a possible future race for leader of the party if, as opinions polls suggest, the Conservatives lose the election expected next year.

The Labour Party has consistently held an around 20-point lead in the polls, and Sunak has failed to reduce that gap.

He tried to relaunch himself as a representative of “change” at his party’s conference last month, when his message was overshadowed by a poorly communicated decision to cancel part of the country’s biggest rail project.

Labour had called Sunak weak since Braverman’s article was published on Wednesday. Now, opposition lawmakers said his decision to appoint Cameron was an act of desperation.

Lawmaker Pat McFadden, Labour’s national campaign coordinator, said: “A few weeks ago Rishi Sunak said David Cameron was part of a failed status quo, now he’s bringing him back as his life raft.”

“This puts to bed the prime minister’s laughable claim to offer change from 13 years of Tory failure.”
