The EU statistics office said that the 4.4 percent deficit in Portugal was the third highest after Greece (7.5 percent) and Spain (5.1 percent).
The other three countries with deficits of over 3 percent of GDP were the UK (4.3 percent), France (4.1 percent) and Croatia (3.3 percent).
In terms of public debt, Italy had the highest ratio (177.4 percent of GDP), followed by Portugal (129 percent), Cyprus (107.5 percent) and Belgium (105.8 percent).
Portugal and Spain are under the excessive deficit procedure and run the risk of having structural and investment funds suspended, even though the fines have been suspended.
