Deadline for Russia in Nerve Agent Saga

Available for over a year

Russia has denied that it was responsible for using a rare nerve chemical on a double agent and his daughter, both found unconscious in the UK. We speak to Bill Browder from Hermitage Capital, who was the adviser to the largest foreign investment fund in Russia until 2005. His experiences have led him to lobby western governments to freeze assets of those involved in institutionalised crime, and he tells us what he thinks of this latest saga, based on his experiences from working in the country. Also, Africa has the youngest population of any continent in the world and that figure is expected to double in less than 30 years. Is it a ticking tomb bomb of unemployment and potential unrest? The BBC's Tamasin Ford goes to Liberia to speak to young Africans. And finally, we find out how to recycle the unrecyclable. Our reporter Vivienne Nunis looks at the problem of the increasing amount of plastic product packaging which ends up in the oceans, and visits those who are trying to remove plastic packaging entirely from their supply chain - using a pioneering machine that turns plastic back in to oil.
