Euro zone lenders and the International Monetary Fund have reached agreed between themselves to present a common stance to Greece later on Friday in talks on reforms and the fiscal path Athens must take, euro zone officials said. Such a united stance would be a breakthrough because the two groups have differed for months on the size of the primary surplus Greece should reach in 2018 and maintain for years later as well as the issue of debt relief. "There is agreement to present a united front to the Greeks," a senior euro zone official said, adding that the outcome of Friday's meeting with the Greeks was still unclear and it was unclear if Athens would accept the proposals.
