James Davis MW is understood to be moving from senior wine buyer at Greene King to join the Tesco team, reporting to head of BWS Gavin Warburton.
Davis has worked for the pub group for seven years, but was previously wine buying manager at Tesco from 2004 to 2007 and has also held a similar buying role at Costco.
His appointment would again put a Master of Wine at the retailerís helm, following in the footsteps of Laura Jewell MW, who moved to the top job at Wine Australia UK earlier this year.
Tesco will also announce a number of redundancies to the buying team following a head office review.
UK and group wine category manager Alain Guilpain is believed to be leaving the business along with Lucy Clements, wine product development manager, who is moving to Australia to take up a buying role with supermarket chain Coles.
Graham Nash and Charlotte Lemoine are understood to be staying in their roles as product development managers, while James Griswood will continue with a sabbatical he took up with Origin Wines in South Africa in January.†
