Research shows that people in Africa are disproportionately rejected for visas over other nationals. While passport holders from Singapore can sail straight past immigration in many countries they visit.

To understand the unfair disparities that exist between passport holders, we speak to Stephanie Hegarty, the BBC’s global population correspondent. We learn about the new version of the Henley passport index (which lists the strength of passports), and why nationality plays a huge role in shaping the outcome of a person’s visa application, especially to countries in the West.

The BBC’s Tessa Wong, a Singaporean national, explains why her passport ranks the strongest in the world. And Daniel Dadzie, a BBC reporter, tells us about his personal experience of applying for a student visa to study in the UK from Ghana.

After the rape and murder of a female trainee doctor in India, there have been protests across the country. She was killed at work. Doctors held a national strike over the weekend.

Protesters want a stronger law to better protect medical staff against violence, increasing the level of security at hospitals and the creation of safe spaces for rest.

More incidents of rape have made headlines in India since the trainee doctor was killed.

Bebika Dhurve, a dentist who has worked in hospitals, tells us her reaction to what’s been happening.

And Arunoday Mukharji is our correspondent in Delhi. He takes us through the story and what challenges female medical professionals face.

MrBeast is the world's biggest YouTuber with more than 300 million subscribers. He’s built an empire partly through so-called “stunt philanthropy,” where he surprises people with large sums of money or gifts. MrBeast has given waiters thousand-dollar tips, gifted people new cars and houses, and even paid for surgery to help 1,000 deaf people hear for the first time. The recipients’ reactions are then filmed and put on his channel.

Tom Gerken, a BBC technology reporter, explains why some people don’t consider MrBeast’s stunt philanthropy particularly philanthropic and how he — and other YouTubers — make money through advertising and brand sponsorships. He also briefly explains the allegations facing MrBeast and some of his colleagues.

We also hear from Makuochi Okafor, a BBC reporter in Lagos, to find out how the trend is taking off in Nigeria.
