Wales' biggest Pride event has banned political party involvement in solidarity with the transgender community.
Pride Cymru said this was in "response to community feedback" and a request from the Trans Safety Network to "ensure the safety" of attendees in Cardiff.
Earlier this week, Birmingham, Brighton, London and Manchester Prides announced that political parties would not be welcome at their events in an official capacity until they demonstrated a "tangible commitment to trans rights".
The announcement comes after the Supreme Court ruled that the term "woman" in the Equality Act was defined by biological sex.
The ruling was welcomed by some campaigners representing lesbian, gay and bisexual people who say it protects single-sex groups, while others shared concerns about the impact on the trans community.
Pride Cymru said individuals who belong to political parties can attend the event on 21 and 22 June, but not as representatives.
In an open letter urging organisers to ban political involvement, the Trans Safety Network said: "Our trans, non-binary and intersex communities are under an ideological attack right now. Politicians are openly debating how to remove our basic human rights.
"Pride is and always has been a protest. It is a chance for all members of the LGBTQIA+ community to show solidarity."
