- Weir and Sage fall heavily- ITV, Sainsbury, Glencore higher after updates- Footsie hits new YTD lows on euro concernsLondon's blue chip index had sunk to levels not seen since late December by Wednesday lunchtime, as political uncertainty in the Eurozone continues to cloud the outlook for the global economy.Stocks across Europe were being sold off today, with Spain's IBEX 35 benchmark down over 3%. By midday in London, US stock futures were also pointing to a weak start on Wall Street as euro area politics fuelled concerns over the global economic recovery.Yesterday's sell-off was spark by the ongoing worries surrounding the political situation in Greece. Antonis Samaras from the Conservative New Democracy failed to form a new government after elections at the weekend. This now means that Alexis Tsipras from the left-wing Syriza party has now been given the task of crafting a coalition. He is expected to reject the tough austerity measures agreed as part of the country's €240bn bailout by the European Union and International Monetary Fund. Tsipras is expected to meet with Samaras and former Finance Minister (and Pasok part leader) Evangelos Venizelos later this evening. "He [Tsipras] interprets, with unbelievable arrogance, the election result as a mandate to drag the country into chaos," Samaras has said. "I hope Mr Tsipras will have come to his senses by the time we meet."The rejection of the austerity package "would effectively lead to a default as early as next month, followed by Greece leaving the Eurozone. The effect this could have on Spain is the most concerning given their struggling banking system following the bursting of the housing bubble," said analyst Craig Erlam from Alpari this morning.
