The chief legal counsel at APG, the biggest Dutch pension fund manager, who spearheaded the €424 billion firm's lobbying efforts against the Financial Transactions Tax and stringent EU rules on derivatives, has announced his departure from the firm.

In an email statement, Guus Warringa said that "after seven intensive and beautiful years I will resign as per September 1, 2015". He thanked APG colleagues for "very beautiful and enriching experiences" but said it was "time for the next step".
