Swiss senators approved on Thursday 8 June the establishment of a parliamentary commission of inquiry into the acquisition of Credit Suisse by UBS. The controversy focuses on possible "deficiencies found at the institutional level" This is only the fifth establishment in Parliament's history.

The questions will be many: how much did this rescue really cost the Swiss taxpayer, what is the cost in terms of jobs and what other solutions could have been put in place upstream to prevent this from happening again in the future.
