Greek regulators have allowed Attica Group to buy the 48.5% stake it didn’t already own in local rival Hellenic Seaways (HSW).

The decision, announced late on Thursday, is the epilogue to a longstanding feud over HSW that pitched interests aligned with the company’s previous management against Italy’s Grimaldi Group, which had amassed the 48.5% stake in a failed bid to wrest control of HSW.
