David Cameron recruits Boris's brother for Number 10 Senior sources said that Mr Johnson's appointment marked the beginning of a more "Thatcher-style" policy unit at the heart of Government. Mr Johnson will be based in Downing Street and will work on Conservative, rather than Coalition, policy. Nick Clegg already has civil servants and advisers drawing up Liberal Democrat plans to be adopted by the Coalition. A Conservative source said: "These appointments clearly represent a more political policy operation and a more Thatcher style Downing Street Policy Unit. The Advisory Board will strengthen the connective tissue between Downing Street and the Parliamentary Party, and Jo Johnson will be a great asset in helping the Prime Minister drive Conservative policy priorities throughout Government. Although overshadowed by his high-profile brother, Jo Johnson, a former journalist for the Financial Times who only entered Parliament in 2010, is regarded as a fast rising Conservative star. Like Mr Cameron, he attended Eton College before Oxford University, where he was a member of the notorious Bullingdon club. The London mayor's youngest brother, who is married to a Guardian journalist, has been tipped as a potential future Prime Minister and rival for the Conservative leadership to Boris. Mr Johnson will be assisted in his role by a newly-created Conservative Parliamentary Advisory Board. It can be disclosed that members of the panel will include Jane Ellison, Paul Uppal, Nick Gibb and Jake Berry. Peter Lilley, a former Cabinet minister who served under Baroness Thatcher and Sir John Major, has also been appointed to the board. Two of the leading members of the board will be Mr Norman, who spearheaded the successful rebellion against Coalition plans to overhaul the House of Lords, and Mr Eustice, a former press secretary to Mr Cameron who has criticised his European policies. The establishment of the advisory board represents an attempt by the Prime Minister to reach out to the Parliamentary party. Earlier this year, Mr Cameron faced the first serious speculation of a potential challenge for the Conservative leadership. He has faced criticism of being out of touch with many backbench MPs, and a number of disaffected former ministers have criticised his leadership style.
