Donald Trump campaigned hard on illegal immigration ahead of the presidential election and promised voters a major crackdown if they backed him. Since he came to power, the president has issued executive orders to fortify the country’s borders and suspend the entry of undocumented migrants. He has also vowed to oversee the largest deportation programme in American history with criminals and gang members prioritised in raids. The three women we talk to came to the US as children and have lived most of their lives in the country but now they fear being arrested by the authorities and deported. In the week where the US government unveiled a new detention centre for holding thousands of migrants, we also hear from Republican voters who support the president’s policies.

Salma El-Wardany meets young women in Egypt using their voices to amplify their faith – drawing inspiration from the long tradition of female Quran reciters in the country. Following in the footsteps of pioneering women like Sheikha Munira Abdou who was first heard on Egyptian Radio 100 years ago and the renowned singer Umm Kulthum, more Egyptian women are sharing their recitations of the Quran publicly. They’re stepping out of the shadows of a fatwa (an Islamic ruling on a point of Islamic law) that denounced women’s voices something to be covered or not heard, which led to a ban of public recitation on the radio in the 1940s. The ban lasted years but the tradition is being restored thanks to a new generation.

British-Pakistani pharmacist turned comedian Lubna Kerr hears from doctors, sufferers, and experts as she explores Pakistan’s growing diabetes crisis. With type 2 diabetes rates now the highest in the world, the disease is affecting millions - shaping lives, straining healthcare, and raising questions about prevention. Many sufferers remain undiagnosed, missing crucial early intervention. But for those who do receive a diagnosis, the ability to monitor blood sugar levels regularly is crucial. Lubna hears about patients who struggle to access glucose monitoring kits, essential for adjusting diet and medication. While urban hospitals offer testing, high costs and limited availability mean that many people, especially in rural areas, are left without the tools they need to manage their condition effectively. Lubna explores attitudes toward diabetes and diet - and how myths and stigma prevent people from seeking diagnosis or treatment.

An inspiration, a politician, a pioneer on and off court - these just some of the words used to describe Arthur Ashe, who became the first African-American to win the men's Wimbledon singles title against Jimmy Connors in 1975.

It was one of the most iconic sporting moments of the 20th Century at a time of huge political and racial unrest.

Ashe’s life spans America’s Civil Rights struggle, the ending of South Africa’s system of apartheid and his creation of an awareness of the disease that would eventually kill him - Aids.

BBC Tennis correspondent Russell Fuller tells his story, hearing from amongst others, former players John McEnroe, Serena Williams, Stan Smith, his agent Donald Dell and his brother Johnnie Ashe.

Why are Poland's young voters turning to the right? With his veto powers, Poland’s president-elect Karol Nawrocki could halt the pro-EU government of Donald Tusk. Poland is a NATO member and backs Ukraine in the war with Russia. Scaling up security is an issue almost all Poles agree on, yet there are some signs of shifting attitudes - on foreign policy and immigration. We examine the gender gap among voters and the recent election discourse to understand how conflicting priorities and enduring conservative values are shaping the eastern flank of the West.

Poland’s president-elect, Karol Nawrocki, is a right-wing historian, an amateur boxer and a fan of Donald Trump. What will his presidency mean for the region? Kateryna Khinkulova, editor of the newly launched BBC News Polska, explains. Plus, India’s ‘tailor on wheels’ with Anil Kumar reporting for BBC Telugu and the science of smiling with Alassane Dia from BBC Afrique.

Following the recent bombing of Iran’s nuclear sites by the United States, we talk to Iranians living in the US about their thoughts as they watch events in the Middle East from afar. They describe feeling conflicted about the attacks carried out by their adopted homeland. They worry about friends and relatives who could be in danger back in Iran. But perhaps unsurprisingly for an exiled community, they have strong views on the Iranian regime. Shaheen grew up in the US but feels very connected to his Iranian heritage. Fellow American-Iranian Manna thinks about the future of her people, “I feel not just guilt as an Iranian, but shame as an American, because I'm afraid that we just made their standard of living and what they are going to have after this ceasefire so much worse.*
