The Mitcham-based drinks wholesaler, which has been a member of Landmark since 2005, claimed there had been no disagreement with the buying group and had decided to change its strategy. It will leave after a six-month notice period.
Elbrook claimed it had no plans to join another buying group but industry sources speculated that it was likely to join up with rival Today's Group, which is the only other large buying group dealing in alcohol. "The directors of Elbrook C&C have carried out a strategic review of the business and have decided it is in the best interests of the company to tender its resignation from Landmark Wholesale and pursue other opportunities to develop its business," Elbrook said in a statement.
"It has to be stressed that the directors of Elbrook C&C are taking this decision with the greatest of reluctance as they have many friends in the group.
"The directors would like to thank Landmark Wholesale for all their help over five years and to wish Landmark Wholesale well for the future."
