There is one week to go until Britain's historic referendum on whether to leave the EU. We visit Switzerland to find out how business-people there, Daniel Kalt, the chief economist of the banking giant UBS, and Tom de Swann, the chairman of Zurich Insurance, regard their countries' associate membership of the Union. What has the experience been like and what might the lessons be for British voters, who might be aspiring to such a status themselves?

Also, we hear about the rising influence of a new middle class in emerging economies. Could the new hundreds of millions of middle class professionals - many of whom are women - be affecting the shape and nature of economic power in the world of the next two or three decades? Miles Young, the chairman of Ogilvy and Mather, one of the world's biggest advertisers thinks so. He also says that Islamic countries from Egypt to Bangladesh are growth areas we ignore at our peril.
