Philippe Gaydoul, grandson of Swiss supermarket entrepreneur, Karl Schweri, is one of three prominent financiers linked to the launch of a new bank in Switzerland.
Reports in the Swiss media say Gaydoul has teamed up with Marcel Rohner, the controversial former chief executive of UBS, and Thomas Matter, the former boss of local bank Swissfirst.
Gaydoul will take a 9.5% stake in the new venture, which has yet to be named.
