'Historic' Iran Nuclear Deal Hailed

Available for over a year

We assess the likely impact of the deal struck to relax sanctions on Iran. The Iranian energy analyst Mehdi Varzi gives us his take on how global oil markets will be affected, meanwhile Tehran-born businessman Xanyar Kamangar tells us that investors are queuing up to put money into Iran. Also in the programme, we're live in Athens to hear just how divided the people of Greece are over whether its parliament should approve reforms to secure the country's latest bailout package. And our regular economic commentator Roger Bootle assesses how successful the deal is likely to be. Plus we hear from the Ethiopian capital Addis Ababa, where world leaders are discussing how to pay for ambitious new targets towards cutting poverty, pollution and hunger.
