Onwards and Upwards

Available for over a year

Nick Thorpe meets some of the Bulgarian people-traffickers who are still moving migrants into the EU from Turkey, and learns the inside tactics of how the business really works. On a rare visit to Asmara, the capital of Ethiopia, BBC Africa editor Mary Harper sees some surprisingly jaunty sights - yet hears accounts of oppression. During a US presidential election year, which has often been described as brutal and vulgar, Robert Hodierne appreciates some quieter American role models - neither billionaires nor superheroes, just ordinary people doing some good for others. And nearly 2.5 kilometres underneath the Swiss Alps, Imogen Foulkes explains why a new rail tunnel, the world's longest, could revolutionise freight and passenger routes across Europe.
