Paul Coppin has stepped down as marketing director of Byron, the Three Hills Capital Partners-backed burger chain, MCA understands.
Coppin joined Byron in September 2016 after six years as head of marketing at Red Bull. He has left Byron to become UK marketing director at Glanbia Performance Nutrition.
MCA has asked Byron for news of a replacement.
Earlier this month, MCA revealed that the company had appointed Russell Hoare, as its new chief financial officer.
Hoare joins the Simon Cope-led business, which is currently closing a number of sites on the back of a Company Voluntary Agreement, from the listed JKS Oil & Gas, where he was chief financial officer for a year and a half.
