German Chancellor Angela Merkel on Wednesday renewed her call for a tax on international financial markets, insisting she would not give up the fight despite hefty opposition from her global partners. “We will continue to work for a tax on the financial markets,” Merkel said in a stormy debate in parliament on her government’s 2011 budget. “The finance minister is doing this in several discussions and we are going to try to persuade as many countries as possible. Unfortunately, the world is not always as we would wish … but we are not going to give up,” she added. At a meeting of European Union finance ministers earlier this month, members of the 27-country bloc clashed over the idea of imposing a tax of financial market transactions in Europe.
