Ken Hanna, the outgoing chief financial officer at confectionery giant Cadbury, is to join Tesco as a non-executive director.

Hanna takes up his new role with the supermarket giant in April, having announced earlier this year that he was stepping down from Cadbury to become chairman of car retailer Inchcape.

The move has already prompted speculation that Hanna may be in line to take over from Tesco chairman David Reid when the tenure of the 61-year-old comes to an end.

Meanwhile, Tesco has also appointed Jacqueline Tammenoms Bakker, a former director general at the Dutch ministry of transport, as a non-executive director. She begins in her new role on 1 January.

“I am delighted that both Ken and Jacqueline are joining the board of Tesco," said Reid. “Ken is a highly respected finance director and also brings with him considerable knowledge of both developed and emerging markets. Jacqueline's experience in both the private and public sectors, and her strong international background, will be an asset to our board.”

Cadbury this week named Andrew Bonfield, previously finance chief at pharmaceuticals company Bristol-Myers Squibb, as Hanna’s replacement.
