Meanwhile, the Finance Ministry reported that the central government budget deficit had soared to 3.41 percent of GDP in the first five months of 2012, just 0.09 percentage points below the targeted figure agreed with the European Union for the entire year.
Spain has agreed to aim for an overall deficit of 5.3 percent of GDP for 2012 based on a projected 3.5 percent figure for the central government, 1.5 percent for regional governments and 0.3 percent for town halls.
Tuesday's figure, up 30 percent on the same period last year, was due to advance payments to regional governments, increased Social Welfare costs and reduced income, the ministry said.
Spain is battling to slash its deficit, which was 8.5 percent last year, to the EU limit of 3 percent of GDP by 2013.
