BRUSSELS/BERLIN (Reuters) - Germany on Monday voiced support for Greece to stay in the euro zone and the European Commission dispatched a senior official to Athens to persuade it to take on further reforms to salvage its bailout accord. International Monetary Fund chief Christine Lagarde, meanwhile, remained firm that as a lender the IMF could not cut any special deals for the crisis-hit country, which has received three bailouts since 2010. The moves came as the European Commission forecast a large jump in economic growth for Greece of 2.7 percent and 3.1 percent, respectively, this year and next.
