British Prime Minister Keir Starmer on Monday announced he will step down once his party chooses his successor.

Starmer succeeded Rishi Sunak of the Conservative Party in No. 10 Downing St. in 2024.

The Labour Party included a ban on so-called conversion therapy in England and Wales in its elections manifesto. King Charles III in last month’s King Speech that he delivered in the British House of Lords said a transgender-inclusive ban is among the British government’s legislative priorities.

Charles delivered his King’s Speech days after the Labour lost more than 1,000 council seats in local and regional elections. The May 7 vote took place against the backdrop of widespread criticism over Starmer’s decision to appoint Peter Mandelson as ambassador to the U.S., despite his ties to Jeffrey Epstein.

Former Greater Manchester Mayor Andy Burnham is seen as the frontrunner to become Labour’s new leader — and the UK’s next prime minister. Burnham was sworn in as an MP in the House of Commons hours after Starmer announced his resignation.

Starmer in his resignation announcement said he expects his successor will be in place before MPs return from their summer recess on Sept. 1.

King Charles III on Wednesday said a transgender-inclusive ban on so-called conversion therapy in England and Wales is among the British government’s legislative priorities.

“My government will bring forward a bill to speed up remediation for people living in homes with unsafe cladding [Remediation Bill] and a draft bill to ban abusive conversion practices [Draft Conversion Practices Bill],” said Charles in his King’s Speech that he delivered in the British House of Lords.

The government writes the King’s Speech, which outlines its legislative agenda. The British monarch delivers it at Parliament’s ceremonial opening.

“Conversion practices are abuse, and the government will deliver the manifesto commitment to bring forward a trans-inclusive ban on conversion practices,” said the government in an addendum to the speech.

Then-Prime Minister Theresa May’s government in 2018 announced it would “bring forward proposals to end the practice of conversion therapy in the U.K.”

Then-Prime Minister Boris Johnson’s government in 2022 said it would support a ban that did not include gender identity. The decision sparked outrage among British advocacy groups, and prompted them to boycott a government-sponsored LGBTQ conference that was ultimately cancelled.

Prime Minister Keir Starmer’s Labour Party ahead of the 2024 elections included a conversion therapy ban in its manifesto. Charles delivered the King’s Speech against the backdrop of growing calls for Starmer to resign after the Labour Party lost more than 1,000 council seats in local and regional elections that took place on May 7.

Stonewall, a British advocacy group, on April 30 said the government “has failed to meet its own timeline to publish a draft bill to ban conversion practices.”

“We should not have to wait any longer,” said Stonewall CEO Simon Blake in his group’s statement. “Conversion practices are abuse. LGBTQ+ people do not need fixing or changing. They need to hear and feel that government is going to protect their safety and dignity. Not at some random date in the future. No more delays.”

King Charles III on Monday unveiled a memorial to British LGBTQ servicemembers.

The memorial is located at the National Memorial Arboretum in Burton-on-Trent, England. 

“We see all the LGBT+ serving members and veterans of the Armed Forces, and we salute you,” said the Royal Family in a social media post that contained a video of Charles placing flowers at the memorial.

“Throughout the 20th century, gay men, lesbians, and bisexual people were banned from serving in the UK Armed Forces,” it adds.

We see all the LGBT+ serving members and veterans of the Armed Forces, and we salute you. 🌈

“Today marks a historic step for healing and reconciliation,” said the British Defense Ministry.

The BBC notes gay servicemembers could not serve openly in the UK until 2000.

Monday’s ceremony is the first time Charles held an “official engagement” in support of LGBTQ rights. 

His mother, Queen Elizabeth II, gave royal assent to the Sexual Offenses Act of 1967, which decriminalized consensual same-sex sexual relations among men in England and Wales who are at least 21, and to a law that extended marriage rights to same-sex couples in England and Wales in 2014. Elizabeth, among other things, also pardoned Alan Turing, an acclaimed World War II codebreaker and computer scientist who died by suicide two years after his 1952 conviction for “gross indecency.” 

Then-Prime Minister Rishi Sunak in 2023 apologized to LGBTQ servicemembers who “endured the most horrific sexual abuse and violence, homophobic bullying, and harassment, all while bravely serving this country.”
