Wimpey chairman Sir Clifford Chetwood, one of the highest-profile figures in the industry, looks set to leave the company at the end of the year to be replaced by Barclays Bank chairman Sir John Quinton.Last week Wimpey announced the appointment of Sir John as non-executive director with immediate effect.But sources say Sir John is being lined up to succeed Sir Clifford. Sir John is stepping down from the Barclays chair at the end of the year and Wimpey is known to favour making such a major in December.One source said: 'If everything goes according to plan, I certainly expect Sir John to take over from Sir Clifford.'Sir Clifford joined Wimpey as a trainee building manager in 1951. He became a director in 1969 and group managing director of UK construction in 1979.He was Wimpey chief executive from 1982 to 1990 and chairman from 1984. He became non-executive chairman last year and it is this position Sir John will take over.Sir John, who is 62 and chairman of football's newly formed Premier League, has been the butt of much criticism over Barclay's financial performance.But his move to Wimpey, and the prospect of him taking over the chair, has been well received in the City.'This is a high profile, high level addition to the board,' said one analyst. 'His expertise, knowledge and contacts will all be of great benefit to Wimpey.'Sir Clifford was unavailable for comment. In a statement, Wimpey said: 'Sir Clifford remains Wimpey's chairman and no decision has been made as to when that position might change.'
