London's role in Islamic finance market

Prime Minister David Cameron has said he wants London's Stock Exchange to be at the centre of the Islamic financial market.

He has also announced plans to open an Islamic Index of companies and cash in on a sector that has seen a 150% increase in investments over the past seven years and is estimated to be soon worth £1.3 trillion.

Deputy mayor Edward Lister outlines why London is a good place for Islamic investors; Azeemeh Zeheer from Gatehouse Bank explains how it would work while Emran Mian from Social Market Foundation says the system has to have a complex structure so that no interest can be made - something which goes against Sharia Law.
