Former Cadbury chairman Roger Carr was knighted for services to business.
Sir Roger was on the Cadbury Schweppes board for seven years before being made chairman of Cadbury in February 2008 when Cadbury and Schweppes split into two. He was chairman until Cadbury was sold to Kraft Foods in March last year.
However, his knighthood has sparked controversy with union Unite claiming that he "does not deserve any awards".
"Unite members working on Cadbury sites in the UK and Ireland will be surprised and disappointed to learn that Roger Carr is being honoured," said Jennie Formby, Unite's national officer for food and drink. "He allowed this iconic British company to be taken over by Kraft, which has already cut hundreds of jobs, with more expected, to pay off their debts."
Alastair Sykes, former chairman and CEO of Nestlé UK, was appointed CBE for services to the food industry. Also honoured was Colin Smith, chairman of Poundland and former chairman of Assured Food Standards, who was appointed OBE for services to Assured Food Standards. Richard Longthorp, a pig farmer and chairman of the Agri-Skills Strategy Group, was appointed OBE for services to the farming industry.
