The EU Commission has extended its probe into the relationship between the international brewers Carlsberg and Heineken N.V.

In a statement Carlsberg said the investigation is intended to complete investigations already carried out by the Commission concerning alleged relations between Carlsberg and Heineken during the period 1993-96.

Carlsberg said it is not obliged to let the Commission carry out the supplementary investigation, but it has cooperated loyally with the Commission throughout the investigations and will naturally continue to do so.

In a similar statement Heineken said: "This inquiry has been on-going for some time. Heineken received a statement of objections from the European Commission on the 1st of March this year and replied to it in May 2002. Heineken is fully cooperating with the inquiry. Pending the proceedings Heineken will refrain from further comments."
