A strike at two Remy Cointreau plants is putting the group's Cognac business under pressure, a senior executive has said.

The industrial action involves around 90% of employees at two sites in Merpins, which produce brands across the entire range of Remy Martin Cognacs. The strikers are demanding a pay rise of €150 a month.

Speaking to news agency AFX, Jean-Francois Boueil, human resources director at the group, said: "We are at a point where orders are significant in October, and every passing day puts us in a difficult position with regards to our clients."

The strike action has included the blocking of supply trucks to and from the two sites.
