A Cardiff hotel has cancelled a debate organised by the campaign group, A Woman’s Place.
In a tweet, which has now been deleted, the Mercure Cardiff Holland House said it is because it does not tolerate any "racist, sexist or bigoted behaviour".
The event had been organised to discuss proposed changes to the 2004 Gender Recognition Act to make the process of legally changing gender more simple.
A Woman's Place said it planned to have a "respectful and evidence based discussion about the impact of proposed changes to the Gender Recognition Act".
The group also said, "The accusation of transphobia should not be used to shut down women's voices".
This led to calls for the event to be cancelled from transgender support groups.
One of the founders of A Woman's Place described the Tweet from the Mercure Hotel as "defamatory".
Abuse, victimisation and hate crime against trans people is on the increase. Much of this is down to misinformation and hate speech spread by a vocal minority of anti-trans campaigners who have gained a great deal of attention in the media and online. The hate campaigns are coming to Wales threatening to create a more hostile and abusive environment for trans people.
The Mercure Cardiff Holland House has since issued a statement saying that the original tweet was "unauthorised", and that the decision to cancel the event had been taken "in the best interests of hotel guests and staff after concerns were raised about their safety, which is our priority, due to potential disruption and protests."
The decision in no way implied any judgement on the views of those organising the event, or those protesting against it. While we are a leader in encouraging diversity and inclusion in all its forms, it is not our policy to pass comment on the view of others.
