Hello, I'm Rosak Kins.

Each week on the BBC World Service, I look at one of the biggest issues in the news.

It's a story of two countries and of two cities.

In Tehran, the British Iranian charity worker Nazanine Zagari Ratcliff has been detained

since 2016.

In London, her husband Richard began a hunger strike in October and is making these demands.

In Nazanine, he's held over some debt, some money, the British government owes the Iranians.

She's not going to come home until they get to pay it, so that needs to be sorted.
