Labour calls for changes to lobbying law after Greensill row

Party says rules should be widened to include in-house' roles such as that carried out by David Cameron

The law must be changed to prevent the type of lobbying undertaken by David Cameron on behalf of the financier Lex Greensill, Labour has argued, after more details emerged about the extent of Greensill's influence inside Cameron's government.

Only external lobbyists who deal with the government are required to be on a formal industry register, and not so-called in-house" lobbyists like Cameron, who took an advocacy role for Greensill Capital after leaving Downing Street.
