Treaty banning nuclear weapons ratified

An international treaty banning nuclear weapons will come into force in three months' time, after it was ratified by the required 50 countries. The UN Treaty on the Prohibition of Nuclear Weapons bans their use, as well as their development, production, testing and stockpiling. But key nuclear states are not signatories, including the United States, Britain, France, China and Russia. 

Also in the programme: A big protest is planned in Belarus and Britain's first mainly black, Asian and ethnically diverse orchestra.

Joining Paul Henley to discuss these and other issues is Colleen Graffy, former US Deputy Assistant Secretary of State and Associate Professor of Law at Pepperdine Caruso School of Law; and Alex Andreou, actor, writer, presenter of The Bunker podcast and columnist for Byline Times.
