Demonstrators shout slogans in front of Spanish Socialist Party (PSOE) headquarters in Madrid December 3, 2010, during a protest against measures announced by Prime Minister Jose Luis Rodriguez Zapatero this week involving the sell-off of parts of its airport and lottery businesses to raise funds. Spain's government is planning to raise tobacco taxes, a government source said on Friday, as it fights to cut its high budget deficit and calm investor concerns that it could need a financial bailout like Ireland and Greece. The banner reads "AENA no privatization against segregation of airports and air navigation". REUTERS/Andrea Comas (SPAIN - Tags: CIVIL UNREST POLITICS)
