The International Olympic Committee (IOC) says eligibility will be determined by a 'once-in-a-lifetime' sex test, which would prevent transgender women and those with differences in sexual development (DSD) who have gone through male puberty from competing in women's events. We hear from former Olympic swimmer Sharron Davies who supports the move, and UN Special Rapporteur Alexandra Xanthaki who opposes it.
Also on the programme: Should foreign tourists visiting our museums be charged for entry? And the hunt is on in Hampshire for Samba, a nine-month-old capybara, who escaped Marwell Zoo over a week ago.

A California jury has found the social media giants Meta and Google liable for harming a young user's mental health by deliberately making their products addictive. We hear from a former Facebook employee.
Also on the programme: amid talk of peace, many Iranians continue to flee their country. We hear from one who took part in January's bloody anti-regime protests.
And: the BBC has a new director general. Will the appointment from the world of tech help the corporation navigate a changing media landscape?

Donald Trump says negotiations to end the Iran war are happening "now" and the "people" the US are speaking to "want to make a deal so badly".

We speak to a Republican Congressman about whether the military operation has increased President Trump's leverage.
Also on the programme: calls grow for the government to permit drilling of North Sea oil and gas. And Daphne Selfe, the world's oldest fashion model still working, has died aged 97. We explore how the fashion industry has come to embrace older women.

But Iran's parliamentary speaker denies discussions have taken place, saying "fake news" is being used to "manipulate" the oil markets. We speak to President Trump's former deputy national security advisor KT McFarland and former Obama and Biden era US special envoy for Iran Robert Malley.
Also on the programme: Hong Kong police can now demand phone or computer passwords from those who are suspected of breaching the wide-ranging National Security Law.
And why are so many people obsessed with their pets? Shaun Ley visits the 'Pets & their People' exhibition at the Bodleian Libraries in Oxford to find out.

The UK has agreed to allow the United States to use British bases to launch strikes on Iranian sites targeting the Strait of Hormuz. Prime Minister Sir Keir Starmer previously allowed US forces to use the bases only for defensive operations to prevent Iran firing missiles that put British interests or lives at risk.
Also on the programme: Dame Jenni Murray, who hosted BBC Radio 4's Woman's Hour for more than three decades, has died at the age of 75. Broadcaster Ritula Shah reflects on her former colleague.
