The Belgian brewing group, Interbrew, said yesterday that it would counter a bid from Slovenia's leading brewer, Pivorvarna Lasko, for the country's second largest beer company, Pivovarna Union. Earlier on Wednesday, Lasko launched an audacious takeover bid for Union in which Interbrew already owns a 41% stake. However, an earlier attempt by Lasko to outbid Interbrew for Union had foundered following the intervention of Slovenian regulatory authorities. Interbrew said it expected the country's anti-monopoly regulators to step in to block a Lasko takeover. Lasko has around 50% of the market, while Union has a 40% share.
