Carlsberg, one of the main sponsors of Euro 2004, may see production for its home market hit by a strike as the start of the tournament approaches. About 230 employees at the company's Fredericia plant in Jutland, western Denmark, have been on strike over pay demands since last Thursday. The union at the site wants a 5% wage increase while Carlsberg is offering 3.2%.

The Fredericia plant represents 60% of Carlsberg products for the company's home market. With Denmark participating in the football tournament, which begins this Saturday, Carlsberg risks being unable to satisfy demand for beer in the country.

Beer produced at Carlsberg's other plant in Copenhagen is not able to make up the shortfall because distribution workers have said that they will not break the strike. A Danish labour court has ruled the strike illegal and said it would fine the union.
