Review of the Year 2015

HARDtalk's Stephen Sackur looks back on the big stories of 2015 including conflict in the Middle East and the migration crisis facing Europe. He goes to South Africa, still reeling from a wave of xenophobic attacks, and on to Zimbabwe where he talks to the country's information minister, ending the year in Colombia where he interviews the president of a country trying to reach a peace deal that will end decades of civil war.
