U.S. Senate passes landmark immigration vote

Available for over a year

The U.S. Senate passes a landmark decision on immigration. Plus, Washington curtails trade privileges for Bangladesh, to try to force the government to make factories there safer. And U.S. President Barack Obama is in Africa trying to promote trade in the fastest growing continent, but is he coming too late to the party? The BBC's Rob Young reports from Botswana on how the government is developing the country's diamond trade. And a Japanese man takes a national broadcaster to court, for using too many English words. Throughout the programme we're connecting the time zones with live guests Ralph Silva, of the Silva Research Network in Toronto, and Mark Matthews, head of research at the bank Julius Baer & Co.
