Peter Aikens has retired as the chief executive officer of Matthew Clark plc, but will remain as non-executive chairman for the next two years. Aikens first came to Matthew Clark in 1990. He led the company to become part of Constellation Brands (formerly Canandaigua) in late 1998. Richard Peters is the new chief operating officer, reporting to Tim Kelly, chief operating officer of the newly-formed Constellation International. Peters was the MD of Matthew Clark Wholesale and is credited with guiding that business to double-digit growth over two years in a flat market where margins are tight.
