"[17] In July 2022, NHS England decided to close GIDS and replace it with regional healthcare centres, following the publication of the independent Cass Review.

[18] In response to the decision, Mermaids CEO Susie Green said she was "cautiously optimistic", but expressed concerns that priority would be given to psychological treatments over medical care.

[21][22] The funding was subsequently put under review after criticism of the charity, including by anti-trans activist Graham Linehan,[23] who created a post on Mumsnet calling for members of the forum to email their concerns to the National Lottery.

[24][25] In response to this, on 18 January 2019, YouTuber Hbomberguy began a livestream attempting to 101% complete the video game Donkey Kong 64, with a goal of $500 to be donated to Mermaids.

[30] Marchant and cast members Emmett J. Scanlan and Anna Friel also met families involved with Mermaids to inform their creative processes.

"[38] Mermaids released a statement saying that they have never encouraged teachers "to state that 'tomboys' should be transgender", and that they do not provide classroom talks or lesson materials for schools, contrary to what had been reported in some newspapers.

[4] Following the commencement of the regulatory compliance case by the Charity Commission in 2022, the Department for Education removed Mermaids from its mental health and wellbeing resources for schools.

[39] The charity criticised the UK Government's April 2021 decision to disband the LGBT advisory board without a planned replacement, describing the move as "very concerning".

[40] In June 2021, Mermaids and other charities, including Stonewall, began raising funds to appeal the awarding of charitable status to LGB Alliance, describing the latter group's activities as "denigrating trans people".

The panel would have been part of an event, eventually postponed, for an expected 100 to 150 trainee child psychiatrists organised by Great Ormond Street Hospital and Health Education England.

[46][47] In September 2022, Mermaids was the subject of an investigation by The Daily Telegraph, which accused the charity of offering chest binders to transgender youth without parental consent and to have told users they believed to be as young as 13 that puberty-blocking medications are "totally reversible".

[49] Mermaids responded by saying that they take "a harm reduction position with the understanding that providing a young person with a binder and comprehensive safety guidelines from an experienced member of staff is preferable to the likely alternative of unsafe practices and/or continued or increasing dysphoria".

[52][53] Mermaids subsequently submitted a number of serious incidents reports to the commission in relation to issues raised in the media, and also closed its helpline temporarily due to what it described as "intolerable abuse" received by staff and volunteers.

The report found no evidence that Mermaids had inappropriate connections with the controversial GIDS service at the Tavistock Centre or with private medical practices, nor had they failed to implement proper safeguarding policies.

[60] Orlando Fraser, the chair of the Commission said: "We have carefully scrutinised Mermaids' activities through a statutory inquiry and have found mismanagement in a number of areas.

The commission has also confirmed, as we have repeatedly asserted, that we have not provided medical advice or acted improperly in our work with children, young people and their families.

"[60][9] In October 2022, Dr Jacob Breslow of the London School of Economics resigned as a trustee of Mermaids after it was revealed he had spoken at a conference organised by B4U-ACT, a paedophile support group, as a PhD student in 2011.
