Michel Péretié, the former chief executive of corporate and investment banking at Societe Generale, has re-emerged almost a year after leaving the French bank, as joint chief executive of alternative asset manager RiverRock European Capital Partners.

Péretié, who has been described by Financial News columnist William Wright as "an urbane banker with perfect English and plenty of international experience", started today at RiverRock, where he will work alongside founder and chief executive Florian Lahnstein and chairman Roland Berger.
