Turkey threatens to allow refugees into Europe

The Turkish President Recep Tayyip Erdogan has vowed to allow refugees to travel on to Europe from Turkey.

Also in the programme: Joe Biden clinches his first ever win in a primary in South Carolina where voters picked the Democratic Party's flag-bearer to challenge Donald Trump for the presidency.

Joining Celia Hatton to discuss these and other issues are Dayo Forster, a Gambian-born writer and international development consultant based in the UK, and Julie Norman, a Teaching Fellow in Politics and International Relations at University College London.
