DUESSELDORF (Reuters) - Germany's Ceconomy (>> Ceconomy), Europe's biggest consumer electronics group, is making a big push to try to resolve a long-running dispute with a major shareholder, its chief executive said on Wednesday.

Analysts have speculated that settling the dispute could allow Ceconomy to pursue a more aggressive acquisition strategy, with the European consumer electronics market seen as ripe for a shake-out due to competition from online players like Amazon.

Ceconomy's shares, which jumped last month after the death of Kellerhals on hopes that his heirs would be able to reach an agreement, were up 1.25 percent at 1044 GMT.

Ceconomy, which split off from retail conglomerate Metro (>> Metro) in part to allow it to become more active in acquisitions, last year took a 24 percent stake in French rival Fnac Darty (>> Fnac Darty).

However, Kellerhals had said Ceconomy could not increase its stake in Fnac Darty above 25 percent due to past agreements between Metro and his Convergenta holding company.

Speaking at the annual general meeting, CEO Pieter Haas said it was the interest of both parties to try to find a solution with Convergenta, the holding company of late German billionaire Erich Kellerhals, co-founder of Media Markt.

Kellerhals, who died in December, held a stake of just over 21 percent in Media-Saturn, and had been at odds with Ceconomy over the management of the business, most notably its move into the online market as well as its split last year from retail conglomerate Metro.
