Farmers gathered yesterday at a square in the central Greek city of Karditsa, demanding that the government increase financial support for the sector. Among the demands put forth by farmers are tax breaks on gas expenses and benefits aimed at helping to offset the falling prices of their products. Producers are also calling for the conservative government to intervene and help break what they describe as a cartel among the wholesalers that buy their products. Meanwhile, other farmers from the district also cut off traffic on the nearby Larissa-Trikala national highway for about 30 minutes as part of their protest action. They were expected to convene late yesterday to decide on subsequent protest action, to be held over the next few days.
