More than 100,000 people packed Lisbon's vast Palace Square on Saturday in the largest rally against austerity and economic hardships since the country resorted to an EU/IMF bailout last May, and organisers vowed to step up protests and labour action, according to Reuters. The mass rally occurred just four days before Portugal's international lenders were due to start the quarterly evaluation of the bailout implementation on Wednesday in the finance ministry building which overlooks the square by the river Tagus. They come amid concerns Portugal may need more bailout funds, if not a debt restructuring like Greece. "We take this opportunity here to make our own evaluation on behalf of those who suffer daily," Armenio Carlos, head of the country's largest union, CGTP, told supporters as the crowd chanted: "IMF doesn't call the shots here!" "We have to step up the struggle," he said. Carlos promised the next wave of rallies across Portugal as soon as on Feb. 29. "The country needs to remove the rope from around its neck," he said, saying that Portugal should try to renegotiate its debt rather than impose more austerity, an argument he has made consistently. The peaceful rally under the banners of the 750,000-strong CGTP, which last month refused to sign a pact with the government on labour market reform, showed that social strife is running strong and likely to grow even though other unions agreed to the reforms demanded by the bailout terms. Spending cuts and tax hikes needed to meet the fiscal terms of the bailout have caused the worst recession in Portugal since the few turbulent years that followed the 1974 return to democracy. Unemployment is at a record of around 13 percent.
