The European Central Bank has left eurozone interest rates unchanged at 1.25% following a meeting in Helsinki in Finland. ECB president Jean-Claude Trichet has signalled that the bank will not raise its main interest rate again next month. He said the bank continued to see upward pressure on inflation, particularly from food and energy prices and the bank would 'continue to monitor very closely' all developments on prices. Analysts were waiting to hear whether Mr Trichet would say that the bank would remain 'vigilant' on inflation, a code word usually seen as signalling a rate hike in the following month. Rates are still expected to rise later in the year, however, possibly as early as July. In the past, the ECB regularly used the 'vigilant' phrase to signal a hike was only a month away. Mr Trichet did so in March, a month before the bank raised rates for the first time in two years. The bank has made it clear that rates are going up to contain inflation, even though higher borrowing costs could make life harder for bailed-out Greece, Portugal and Ireland. The bank also kept two other benchmark rates, the marginal lending rate and the deposit rate, unchanged at 2% and 0.5%. In Portugal, International Monetary Fund and European Union negotiators have unveiled terms of the eurozone's latest financial rescue package. The measures include reform of Portuguese laws protecting the labour market and cuts in the amount and duration of unemployment benefit, but also a reduction of charges on employment. In throwing a lifeline to Portugal, EU officials are trying to keep the debt crisis from pulling down a much bigger member, Spain. When asked about remarks by former Finance Minister Brian Lenihan that Ireland was pressurised into applying for a bailout, Mr Trichet said he would not comment on such remarks. However, he added: 'The level of commitment by the eurosystem towards Ireland has been absolutely without precedent. 'The level of commitment towards Ireland has absolutely no precedent. 'The facts speak for themselves. We are siding with Ireland In the difficult circumstances. '
