Former Credit Suisse chair Sir António Horta-Osório has joined Cerberus Capital Management as a senior adviser in Europe, adding to a set of new roles since his sudden departure from the Swiss bank in January.

His job will be to help the US private equity firm with deals in Europe's financial sector, drawing on his relationships from decades in banking, people familiar with the matter said. The appointment came about because he knew some of Cerberus's top executives from other assignments, one of the people said.
