Glasgow Pride has banned political parties from this year's festival over a perceived lack of action in response to the recent Supreme Court gender ruling.
Organisers said politicians had failed to speak out or provide clarity after the UK's highest court said a woman was defined by biological sex under equality law.
Parties will not be allowed to register for a space or host a stall at the annual LGBT+ march on 19 July, with politicians banned from making speeches.
It follows announcements earlier this week by Pride groups in Birmingham, Brighton, London and Manchester in a gesture of solidarity with the transgender community.
The Glasgow parade has attracted as many as 50,000 people in recent years.
Politicians can still attend the event, but will be expected to do so as individuals or as elected representatives of their local community rather than their party.
Glasgow's organising committee acknowledged that many politicians had been very supportive of the event in the past.
But it said it had been forced to act in response to a "lack of action and delay of comment from parties" in the wake of the Supreme Court ruling.
