The process of finding a new Tesco (TSCO) chairman looks far less like the coronation it seemed two weeks ago, with observers now picking late entrant Archie Norman as favourite for the post.

A number of reports today suggest that the former Asda chairman has emerged as the frontrunner ahead of former Dixons chairman John Allan, who had looked a shoe-in for the role when Sir Ian Cheshire, the former chief executive of Kingfisher, pulled out of the race two weeks ago.

The Financial Times today writes that two Tesco’s top-10 investors are pressing the company to go with Norman, with a decision expected to be made by the company as early as this week. The potential appointment has already won the support of analysts, with Norman being described as a “credible figurehead”.

If Norman is appointed, it would throw up the intriguing scenario of the pair credited with Asda’s spectacular turnaround in the late 1990s both taking new chairmanships of rival grocery retailers. Former Asda chief executive Allan Leighton is poised to become chairman of The Co-operative Group.
