ECB's German representative and chief economist Jurgen Stark resigned from the ECB's Executive Board to express his opposition to ECB bond purchases of sovereign bonds of Greece, Spain and Italy. This follows the resignation of Axel Weber as head of the Deutsche Bundesbank in June 2011, who raised similiar concerns. The concern is that the ECB is exceeding its charter by buying sovereign bonds, taking on a political role and adding new risks. Stark wrote in an op-ed in the German newspaper Handelsblatt- as government efforts so far have failed, "far-reaching reform of the mechanism for decisions and sanctions is needed... We find ourselves in a situation in which massive sustainability risks in public budgets are eroding financial stability."
