LONDON — British Prime Minister Keir Starmer headed Sunday on a tour of the four corners of the U.K. as part of an “immediate reset” with governments in Scotland, Northern Ireland and Wales.

Starmer, who said he has a “mandate to do politics differently” after his party’s landslide victory, made his first stop in Edinburgh to meet with Scottish First Minister John Swinney to “turn disagreement into cooperation.”

“We will serve every single person in Scotland,” Starmer told a group of enthusiastic supporters. “Performance, self-interest: they’re the politics of the past. The politics of this Labour government of 2024 is about public service, restoring standards of making sure that we always, always have in our mind’s eye the people who elected us into government.”

While each of the devolved nations in the U.K. elects members to the House of Commons in London, they also have their own regional parliaments.

Starmer’s Labour Party trounced Swinney’s Scottish National Party for seats in Parliament. However, pushing for Scottish independence, the SNP still holds a majority at Holyrood, the Scottish parliament.

The trip to build better working relations across the U.K. is part of Starmer’s broader mission to work toward serving people as he tackles a mountain of problems.

The Labour government inherited a wobbly economy, leaving Britons struggling to pay bills after global economic woes and fiscal missteps. It also faces a disenchanted public after 14 years of chaotic Conservative rule and fiscal austerity that hollowed out public services, including the revered National Health Service, which Starmer declared broken.

Starmer said he wants to transfer power from the bureaucratic halls of government in London to leaders who know what’s best for their communities.

After his brief tour, he’ll return to England, where he plans to meet with regional mayors. In his first news conference Saturday, he said he would engage with politicians regardless of their party.

“There’s no monopoly on good ideas,” he said. “I’m not a tribal political.”

Starmer continued to speak with other world leaders, having separate calls with Israeli Prime Minister Benjamin Netanyahu and Palestinian President Mahmoud Abbas.

He spoke with both about his priorities for a cease-fire in the Gaza Strip, the return of hostages to Israel, and an increase in humanitarian aid, a spokesperson said.

He told Abbas that recognizing a Palestinian state as part of a peace process was the “undeniable right of Palestinians” and told Netanyahu it was important to ensure the long-term conditions for a two-state solution, including ensuring financial means for Abbas’ Palestinian Authority to operate effectively.

Labour’s initial refusal to call for a ceasefire last year is blamed for costing it support and some seats in Thursday’s election.

In advance of Starmer’s attendance Tuesday at a NATO meeting in Washington, the U.K.’s top diplomat reiterated an “unshakeable” commitment to the alliance during his first trip abroad.

Foreign Secretary David Lammy said during a visit to Poland, Germany, and Sweden that the U.K. government would tighten relations with the European Union and remain “ironclad” in its support for Ukraine.

“European security will be this government’s foreign and defense priority,” Lammy said in Poland. “Russia’s barbaric invasion has made clear the need for us to do more to strengthen our own defenses.”

Lammy reiterated Starmer’s pledge not to rejoin the EU single market after British voters voted to break from the political and economic union in 2016.

“Let us put the Brexit years behind us,” Lammy told The Observer. “We are not going to rejoin the single market and the customs union, but there is much that we can do together.”

Business Secretary Jonathan Reynolds said Sunday on Sky News that the U.K. should look for ways to improve trade with the EU and that removing some trade barriers was sensible.

However, he said the Labour government was not open to the free movement of people required to be a union member.
