Master of Wine Laura Jewell has taken up her new role as senior product development manager for Tesco.

The Grocer revealed in July that Jewell was leaving Spar to join the retail giant.

"My time at Spar has given me a fresh perception of the wine industry," she said. "I look forward to ­using that experience and leading product development and innovation."

She joins Graham Nash and James Griswood in Tesco's development team, and will cover Australia, Germany, Portugal and Champagne. Griswood will be responsible for Spain, South America, US, western France, eastern Europe and England, while Nash will cover South Africa, Italy, eastern France and New Zealand.

"It is fantastic that Laura has joined Tesco in this critical role," said Dan Jago, Tesco director of beer, wine and spirits.
