A gender critical activist has confronted the trans rights heckler who disrupted a fringe event at the Conservative Party Conference in Manchester live on air on GB News.

Sitting down with GB News, activist Andrew Boff said he interrupted the event to simply offer "a comment where a comment was needed".

Earlier today, a gender debate was disrupted by a trans rights activist during a discussion at the Conservative Party conference in Manchester with Shadow Minister for Women and Equalities Claire Coutinho and former Olympian Sharron Davies.

Their chat was interrupted by the man wearing a trans rights T-shirt who repeatedly sought to make his point during the debate on trans women taking part in biological women's sports.

"In the conference handbook in the agenda, it said it was a debate," he argued, adding: "It's a funny old debate when there's only one side of the argument."

"So far, walking around, I've had a lot of support from people because even if people don't agree with my view, they do agree with free speech.

"A debate should have two sides to the argument. You should hear the other side. There was no other and I just made it a debate," he added.

Just as he was speaking, GB News Political Editor Christopher Hope invited Marion Calder, who is director of For Women Scotland and the recipient of Mr Boff's heckling, to hit back at her new debating partner.

While initial interactions between Mr Boff and Ms Calder showed their mutual support for free speech, the heckler soon turned to share his criticism of what he claimed to be a heavily one-sided debate.

"I wouldn't have needed to have heckled if the other side of the argument was on the stage," Mr Boff argued, adding: "But it wasn't, was it?"

"I didn't hear about how you were going to include trans people in any decision," he continued.

Fervently hitting back, Ms Calder said that this was because the debate centred on women's rights, disagreeing that the debate was about trans rights.

While she was speaking up on stage, she said that it was "very disconcerting when you're actually having a singular male voice coming from the crowd".

Quick to interject, Mr Boff asked: "How do you know what my sex is?"

Almost incredulously, the women's rights campaigner asked him to repeat himself, calmly retorting: "I can look at you and I make a gauge on the size of your hands. I look at your beard and I will make a decision."

"That's how I decide to treat people, based upon what they look like and how they treat someone," Mr Boff agreed, adding that he also considers how an individual identifies.

Ms Calder hit back, saying "that's now how life really works", explaining how women have to make these sorts of decisions on a daily basis just on being able to identify an individual's sex.

"Now, unfortunately, people don't go around saying, I'm a good person, I'm a bad person. So women do have to make that decision on the basis of sex because it's just self-preservation," she argued.

She asserted that, as trans women are biological men, statistics do not show that trans women are any less likely to be a risk to women than cisgender biological men.

The debating duo then began talking over one another, culminating in Ms Calder dubbing Mr Boff's claim to be "ridiculous".
