Kate Adie introduces stories from across Europe, Nepal, Ghana, and Moldova-Transnistria.

As countries across Europe harden their stance on immigration, Fergal Keane retraces the journeys refugees have taken over the years, including stories he has heard from Ireland, Syria, Turkey and Sweden.

Nepal’s government was dramatically overthrown in the deadliest unrest seen in the Himalayan country in decades, triggered by a social media ban and anger at corruption and high unemployment. Charlotte Scarr was in Kathmandu as the protests continued.

Ghana is the world’s largest importer of used clothing, with millions of garments arriving every week, donated from countries like the UK and US – but it’s often the quality, not the quantity which is proving a problem. Hannah Gelbart has been to Accra to see the impact of fast fashion.

And finally, in east Moldova is the self-declared separatist state of Transnistria. Home to around 350,000 people, the region broke away from Moldova in 1990 – though neither Moldova or the international community recognises its independence. Despite the schism, Transnistrians still have a say in what goes on in Moldova - and will be voting in next weekend’s election. Peter Yeung recently paid a visit.
