George Osborne must concentrate on the economy, says Lord Lawson Dismissing suggestions Mr Osborne should be moved to a different role, he said: "I think his last budget was not his biggest success but I think he should continue in that job But I do think...that it would be sensible for him to set aside his second job. In a pointed criticism of Mr Cameron, he said the party leader had "a lot to learn" from Baroness Thatcher's methods - and was out of step with Tory MPs in favouring the recent Labour model. "There are basically two models of long-term premiership in recent memory: Margaret Thatcher and Tony Blair," he suggested. David Cameron has modelled himself very much on the Blair style. I think the Conservative backbenchers prefer the Thatcher style. I do think he has a lot to learn from her. And I think Blair is a bad role model except in that particular time in history of changing the Labour Party which had to be done. He was brilliant at that but I don't think that applies to the Conservative Party at all. I don't think there is any read across. His comments come after David Cameron was urged by local Tory party officials to ditch unpopular policies like Lords reform and attempts to legalise gay marriage, and focus all his efforts on boosting the economy. Analysis compiled by Lord Ashcroft, the Tories' former Conservative chairman, found that more than a third of people who voted Tory in 2010 general election are refusing to back him in the future.
