Steel magnate Lakshmi Mittal, whose donation to the Labour Party sparked the Mittalgate affair, still tops the list, although his personal fortune has fallen from £1 billion to £900 million. The Hinduja brothers, Sri and Gopi, who were involved in another Labour Party embarrassment - the cash-for-passports scandal - are number two for the second year running and their combined wealth has risen from £700million to £800 million.
