Rishi Sunak takes a stand in the trans debate during Piers Morgan interview trends now

Rishi Sunak tonight waded into the transgender sporting row as the Prime Minister declared that 'biological sex really matters'. 

The PM blasted unfairness of transgender athletes competing in women's sport and insisted he 'knows what an woman is - an adult human female'.

Speaking to Piers Morgan on TalkTV, Mr Sunak lashed out at the trans debate, saying 'it doesn't strike most people as being fair'.

'Whether it's sex, whether it's women's spaces, whether it's prisons, biological sex really matters. And actually we saw that recently with what’s going on in Scotland,' Mr Sunak added. 

Asked to define a woman, the PM said: 'I'm married to one. I have two daughters. And it's really important that they grow up in a society where their needs are respected, whether it's, you know, how they want to be treated when they're in changing rooms or sports, but also their safety.'

During his interview, Mr Sunak vowed to tackle the 'ridiculous' Channel migrant situation today as he faced off against Piers Morgan.

In an interview to mark his first 100 days in office, the PM said his blueprint for overhauling the system would see asylum claims heard in 'days or weeks'.

He told Talk TV the efforts to 'break the cycle' included a new deal with Albania - said to be the origin of 30 per cent of illegal migrants - and closer working with France.

And he insisted that the government's plan for sending arrivals to Rwanda for processing will definitely go ahead. 

Ministers have made stopping the flow of small boats crossing the Channel a top priority, with Tory MPs warning that failure to get a grip will be disastrous at the next election.  

Speaking from his home in Downing Street, Mr Sunak said: 'The system that we need, the system that I want to introduce, is one whereby if you come here illegally, you should be swiftly detained and then in a matter of days or weeks we will hear your claim, not months and years, and then we will safely remove you somewhere else. And if we do that, that's how we'll break the cycle.'

Pressed by Morgan on how he would make that happen, Mr Sunak said: 'So, look, in the first 100 days what have we done, what have I done? 

'I've got a new deal with France, which is increasing the amount of patrols that are happening on French beaches, which is making a difference already.
