Max Pearson presents a collection of the week's Witness History interviews from the BBC World Service. Our guest is Dina Esfandiary, Middle East Geo-economics Lead at Bloomberg Economics.

We start in 2015 with insider accounts of the Iran nuclear deal and the Greek debt crisis.

Then, the 1995 'Turbot War' between Canada and Spain.

We hear how international broadcaster Voice of America was born during World War 2.

Finally, the rise of Italo disco in the early 1980s.
