Andy Burnham MP, Labour’s Shadow Health Secretary, responding to reports that Lynton Crosby lobbied Minister days before taking up Tory role, said:   “This revelation leaves David Cameron and Lynton Crosby with serious questions to answer. They have clearly not been straight with people.   "Last summer, Cameron and Crosby led the public to believe that the Tory Election chief had never used his position to lobby the Government on cigarette packaging. But we now know that was not true and that Crosby was lobbying Ministers just days before entering Downing Street.   "This whole affair raises yet more doubts about David Cameron’s judgement and the character of his Government. He brought a tobacco lobbyist into the heart of No10 and then failed to answer straight questions about his activities.   "This matter needs to be cleared up once and for all and David Cameron has serious questions to answer.”   Ends   Editor’s Note:   1. http://www.theguardian.com/politics/2014/sep/06/lynton-crosby-lobbied-for-tobacco-giant-philip-morris
