The Labour Party has been accused of accepting multi-million pound donations under the guise of temporary "loans" from individual business people.
Keith Taylor, Green Party Principal Speaker, comments: "I am appalled that mainstream parties are indulging in such underhand behaviour. The recent report by the independent Power Commission has called for tighter restrictions on the funding of political parties and this latest revelation makes such a move all the more urgent.
"The Green Party does not accept corporate sponsorship, allowing us to be a truly independent party, which refuses to compromise our principles and values. It stretches credulity beyond breaking point to say that these monies were handed over without some expectation of a pay-off. As Bob Dylan once said, "Money doesn't talk, it swears".
