The Czech budget gap in 2009 could reach 50 to 60 billion koruny (2.5 to 3 billion dollars), the CTK news agency reported Thursday citing Czech Finance Minister Miroslav Kalousek. Parliament's lower house Wednesday approved a 2009 budget with a deficit of 38.1 billion koruny (1.9 billion dollars), which relies on a growth of the country's gross domestic product by 4.8 per cent.
