Nick Bunker, the head of Kraft Foods‘ businesses in the UK and Ireland, is to become CEO of United Biscuits recently-separated snacks unit.

United Biscuits said today (6 August) Bunker would become chief executive of KP Snacks on 1 September.

Signs that United Biscuits could be split in two emerged in March when the company told just-food it was creating two business units within its UK structure, a move seen as a potential pre-cursor for the break-up of the company.

Earlier that month, sources had told just-food the move was being considered as a way of “realising more value” for owners BLACKSTONE and PAI Partners, which had put United Biscuits up for sale in 2010 but failed to find a buyer.

According to reports last month, the private-equity firms plan to start the process to sell the UK firm’s salty snacks business after the summer.

Bunker’s appointment will see him rejoin United Biscuits. He worked for the company’s international division in the 1990s. After a stint at retail and services group Inchcape, he joined Kraft in 2000. He worked for Kraft’s businesses in the UAE, the Czech Republic and Slovakia before moving to head its UK arm in 2008.
