The OECD explained that 'uncertainty has become more prevalent' as it cut this year's growth forecasts. It expects 'a delayed recovery, starting this year and gathering momentum in 2004'. It noted OECD government budgets have soared from balance to deficits totalling 3.5% of GDP in just two years. 'This striking turnaround is a cause for concern,' it says. 'There is now a pressing need to put public budgets on a medium-term consolidation course.'
