SHAWN POGATCHNIKDUBLIN (AP) â¿¿ About 10,000 socialist protesters marched Saturday through Dublin in opposition to government plans to unveil Ireland's sixth straight austerity budget. The capital's major boulevard, O'Connell Street, was filled in both directions with marchers, some donning ghostly white masks and Santa hats. The demonstrators were from a wide range of anti-tax campaigns, labor unions and community groups, most of them with a hard-left bent. Many bore banners denouncing government leaders and vowing not to pay new and future tax hikes. "The government can't be given a free hand to cut whatever they like. You have to be willing to get out on the streets and do something," said Lizzy Stringer, a 26-year-old school assistant who marched in a hand-made protest suit emblazoned with words summarizing the personal despair behind Ireland's debt crisis: hunger, depression, suicide. The parade mixed darker themes with gallows humor. A rider on horseback in white mask and black cape depicting Death led the parade, while the horse had a "no to austerity" banner round its neck. On placards Irish leaders were portrayed as serpents, with pleas to St. Patrick to return and banish them from Ireland. Marchers donned Santa hats, some bearing the slogan "No no no!" rather than ho ho ho, and warned that the government wanted to play Grinch and steal Christmas. Ireland faces more protests in the buildup to the Dec. 5 budget, when the government of Prime Minister Enda Kenny is committed to unveiling a further â¿¬3.5 billion ($4.5 billion) in spending cuts and tax hikes in this country of 4.6 million. Ireland already has pledged to keep imposing annual cuts and tax hikes through at least 2015 as part of its austerity program, begun in 2009, to combat yawning deficits and fund a colossally expensive bank rescue program. Ireland's long-booming economy plunged in 2008 as credit-fueled property speculation collapsed, forcing Ireland to nationalize five of its six banks.
