British Labour Party urge probe into 'repulsive' #panamapapers

British PM David Cameron has come under intense pressure to crack down on offshore tax havens after a massive data leak exposed the scale of efforts by the rich and powerful to hide assets.

The British Prime Minister’s late father was reported to be among figures - including six peers, three ex-Tory MPs and political party donors - named in relation to investments set up by Panamanian law firm Mossack Fonseca.

Downing Street said it was a "private matter" whether the Cameron family still had funds in offshore investments and insisted the PM was in the vanguard of efforts to increase the transparency of tax arrangements.
