Trevor Bond has become the MD of Cadbury's newly created BIMA (Britain, Ireland, Middle East and Africa) division.
His appointment is part of a global shake-up of the company, which includes a restructure of the company and the loss of 7,500 jobs.
Cadbury's Europe, Middle East and Africa (EMEA) region is being split into two areas - creating BIMA and a separate Europe division.
Bond will be working with Matthew Shattock, who was appointed as the new director of BIMA on 5 June.
The pair have worked together before on the integration of Cadbury's Adams Confectionery into Americas Confectionery between 2003 and 2005.
"This reorganisation has put the building blocks in place to help us to refocus and revitalise the business," said Cadbury.
Cadbury is also shedding nine of its senior executives as part of the restructuring programme, including the MD of the UK's confectionery division, Simon Baldry, and making thousands of job cuts worldwide.
In a trading statement this week, Cadbury Schweppes chief executive Todd Stitzer announced plans to close 11 of the company's 81 factories by 2011. About 15% of the 53,000-strong workforce will lose their jobs. It is not yet known which factories will be closed.
The T&G, which has more than two thousand members across Cadbury's UK operation, said the potential job cuts were of "grave concern".
"We have worked hard with Cadbury on a change programme, which means the UK factories are extremely efficient," said Brian Revell, T&G section of Unite national secretary for food and agriculture.
"We are concerned by the announcement, which we are convinced is driven by the threat of a takeover by private equity."
