Credit Suisse CEO Tidjane Thiam quits after spying scandal

Credit Suisse CEO Tidjane Thiam has stepped down amid reports of a power struggle following a spying scandal at the bank. Thiam will be replaced by Thomas Gottstein who is currently heading the bank's Swiss business. The scandal came to light in September when company's former star wealth manager Iqbal Khan confronted a private detective following him and his wife.
