The exchange’s main index was down a further 2.7 per cent in early afternoon trading Tuesday.On Friday, farmers from across Greece are planning to travel to Athens, with plans to stage a three-day protest outside parliament.Government spokeswoman Olga Gerovasili said Tsipras was willing to meet farming associations but insisted the “the negotiations cannot start from zero.”Farmers launched the tractor blockades on Jan. 20, and have since stepped up their protests along the nation’s highways and at border crossings, causing long delays for drivers and truckers.Police said Tuesday Bulgarian truck drivers used their vehicles to smash a customs boom barrier at the Greek border with Bulgaria. Four trucks crossed into Bulgaria, while a fifth truck was stopped and the driver arrested on public disturbance charges.The conservative main opposition party called on the government to withdraw the pension overhaul plan to avoid “social upheaval.”__Follow Gatopoulos at http://www.twitter.com/dgatopoulos and Kantouris at http://www.twitter.com/CostasKantouris__Gatopoulos reported from Athens.
