Copland announced his resignation as chairman and board director last week.
He described his decision to reduce his involvement in the international agency as 'amicable and above board'. Copland will still work on a project basis, spending a few days a month on its European business, particularly managing affiliate and partner agencies and overseeing international account management and training.
Pleon won US PR title The Holmes Report's 2007 award for European consultancy of the year. Last year it secured sought-after briefs from online map service Multimap and travel website Ebookers.
Pleon UK chief executive Jennifer Helfer Paavola said Copland would not be replaced immediately, but the agency would consider hiring a new chairman 'at a new stage of milestone growth'.
She added that Pleon would soon be announcing new hires in the senior management of its UK office.
Copland started his tech PR career at Aeberhard and Partners in 1986 as part of a team of five PROs. The agency was rebranded the A Plus Group in the late 1980s before being acquired by Omnicom and teaming up with Brodeur to create Brodeur International.
Pleon was created three years ago as the European arm of Brodeur Pleon Worldwide. The company now has more than 1,000 employees in 76 offices.
Pleon last week followed the lead of fellow global agencies Ketchum and Bell Pottinger by launching a specialist litigation comms practice (PRWeek, 8 January 2007).
