Swiss National Bank chief forced to quit because of wife's insider currency trading

On Monday August 15, just weeks before Mr Hildebrand announced a major intervention to halt the dramatic rise of the Swiss franc, Mrs Hildebrand sold the franc and bought $504,000 (£309,531 based on sterling's value at the time).

This part of the article is particularly hilarious:

Any suggestion that such information was being leaked, enabling insiders to profit from their knowledge, would be disasterous for faith in a central bank's impartiality. For instance, the European Central Bank is clear that no conflict of interest is presented by the fact that Giacomo Draghi, the son of its president Mario Draghi, works as an interest rates trader in the London office of Morgan Stanley.

And the ECB is "clear" about this... how?
