Ian Dunt's UK, the right to sing in Afghanistan, and how salmon got to Tasmania

UK columnist Ian Dunt surveys the strange world of political party conferences in the UK, plus the emerging role of former PM Tony Blair in plans for Gaza. The young Hazara activist Nila Ibrahimi shares her story of fleeing the Taliban, and her fight for the rights of girls and women in Afghanistan. Plus, the mad colonial experiment to bring Atlantic salmon from the northern hemisphere, to Tasmania.
