The managing director of C&C's cider operations in the UK has decided to resign.
John Holberry joined the group just last year from Coors Brewers Limited.
'The appointment of the new management team, headed by John Dunsmore, reduces the opportunities for me to develop my career,' Mr Holberry said.
C&C recently predicted a 23% sales slump in its Magners cider brand in the UK for the year ending February as market conditions in the UK - and Ireland - are, if anything, getting worse.
