Sir Keir Starmer KCB KC is the Prime Minister of the United Kingdom since July 2024 and Leader of the Labour Party since April 2020. [1] His position on trans rights has shifted dramatically over his tenure, from pledging support for self-ID to aligning with anti-trans Supreme Court rulings.
November 2020: Five months after becoming Labour leader, Starmer posted on Facebook:
"Trans rights are human rights, and your fight is our fight too. The Labour Party stands proudly with the trans community." [2]
His position was understood to match the 2019 manifesto commitment to "reforming the Gender Recognition Act 2004 to introduce self-declaration for transgender people." [2:1]
June 2021: In a PinkNews Pride video, Starmer confirmed:
"We're committed to updating the GRA to introduce self-declaration for trans people." [3]
September 2021: When asked on the Andrew Marr Show whether it was transphobic to say "only women have a cervix" (Rosie Duffield's statement), Starmer replied:
"It is something that shouldn't be said. It's not right." [2:2]
March 2022: Asked repeatedly by Nick Ferrari on LBC whether "a woman can have a penis," Starmer refused to answer:
"I don't think that discussing this issue in this way helps anyone in the long run." [2:3]
January 2023: After Scotland's Gender Recognition Reform Bill controversy, Starmer distanced himself from Scottish Labour's support:
"Well that was a matter for Scottish Labour. I'm telling you what the position is in relation to the whole Labour party." [2:4]
March 2023: Following Nicola Sturgeon's resignation, party strategists warned Starmer he would "lose the election campaign on day one" unless he shifted on trans rights. [2:5] He began signaling retreat.
April 2023: Starmer told the Sunday Times:
"For 99.9 per cent of women, it is completely biological... and of course they haven't got a penis." [2:6]
2025: Starmer stated that "trans women are women" — then reversed course, aligning with the Supreme Court's definition of womanhood as "adult female." [4]
2026: Labour banned trans women from attending the party's women's conference following the Supreme Court ruling. [4:1]
Dame Emily Thornberry, former shadow attorney general, has publicly blamed Morgan McSweeney (Starmer's Chief of Staff until February 2026) for steering Labour's anti-trans shift.
From Scene Magazine (March 2026):
"She singled out former chief of staff Morgan McSweeney, who left Downing Street last month, for steering the party into territory that 'didn't come naturally' to Labour MPs." [4:2]
"Labour had stopped 'following our hearts' on trans rights, instead allowing itself to be pushed towards a more socially conservative position by senior advisers." [4:3]
"If the Labour Party doesn't look after trans people, what are we about?" [4:4]
McSweeney resigned in February 2026 over his role in recommending Peter Mandelson as US Ambassador — Mandelson was subsequently arrested on suspicion of misconduct in public office related to his connections to Jeffrey Epstein. [5]
Starmer's rise was enabled by Labour Together, an anti-Corbyn organisation co-founded by Maurice Glasman. [6] Labour Together was funded by hedge fund money and helped deliver Starmer's leadership victory. [6:1]
Glasman has explicitly stated his goal to "reclaim the rainbow from the ownership of transsexuals" and attended Trump's 2025 inauguration. [7]
The EHRC antisemitism investigation into Labour — led by Alasdair Henderson — was used to sideline Jeremy Corbyn and the Labour left, enabling the Starmer/McSweeney faction to consolidate control. [8]
Henderson was simultaneously:
Under Starmer's government:
Labour MPs including Nadia Whittome and Dawn Butler have raised concerns about consequences for gender-non-conforming people who are increasingly harassed in public spaces. [4:8]
