Gendered Intelligence, a national charity for trans people, welcomed the announcement while calling out the prime minister for past comments.
“The UK has its first openly trans MP,” they wrote. “At a time when the prime minister himself treats trans people with disregard and disrespect, this takes courage – and we hope it shines a light for all other trans and non-binary people in Parliament and beyond.”
Johnson reportedly made a joke seen as transphobic at a “champagne bash” with MPs just hours before the announcement, beginning his speech with: “Good evening ladies and gentleman, or as Keir Starmer would put it, people who are assigned female or male at birth.”
At PMQs on March 23, he said: “when comes to distinguishing between a man and a woman, the basic facts of biology remain overwhelmingly important”.
LGBTQ+ charity Stonewall praised Wallis, tweeting: “Well done on taking this step Jamie. You have our full support and solidarity. Love from all of us at Stonewall”.
As did trandsgender support charirty Mermaids, which wrote: “We are moved to hear @jamieWallisMP coming out as on their trans journey. It’s saddening to also read all that he has been through. Congrats on being the UK’s first trans MP, we look forward to working with you.”
Alex Davies-Jones, MP for nearby Pontypridd, was among the first to respond, calling Wallis’ statement “incredibly brave and powerful”.
The sentiment was echoed by Foreign Secretary and Women and Equalities Minister Liz Truss, who told Wallis: “We stand with you.”
Labour’s Wes Streeting also wrote that he was sending “love and solidarity from the other side of the commons”, but Twitter users quickly pointed to a recent interview in which he was applauded for saying: “Men have penises, women have vaginas. Here ends my biology lesson.”
Labour MP Olivia Blake, wrote: “I don’t think we’ve ever crossed paths but I wanted to say as a fellow LGBT+ MP that this is an incredibly brave and honest statement. I hope this is met with only kindness and understanding.”
