Belgian supermarket group Delhaize is to buy the outstanding 34.7 per cent stake in its Greek subsidiary Alfa-Beta.

Delhaize said it would offer E30.50 (£26.88) a share. It became the principal shareholder of Greece’s second-largest food retailer in 1992.

Delhaize chief executive Pierre-Olivier Beckers said he intends to operate Alfa-Beta with “no major changes to its current business model or strategy”.
