Cadbury chief financial officer Ken Hanna has signalled his intention to leave the UK confectioner in April next year.

After five years with Cadbury, Hanna said that he wanted to pursue a number of non-executive appointments, including becoming chairman of car retailer Inchcape.

"I have every confidence that, as a focused confectionery company, Cadbury will deliver on its full potential," Hanna said.

An external search for Hanna's replacement has begun.

Shares in Cadbury dropped 2.03% following the announcement to GBP5.54 (US$9.86) at 13:00 BST.
