"Compliance to the rules ensures medium-term sustainability of public finances, allowing to reduce the debt of the government's sector," Šapoka said in a press release.

The government has already given its initial backing to the 2018 budget draft, which is for the first time projected with a general surplus of public finances. The bill was submitted to the parliament on Tuesday.

The 2018 budget revenue is projected at 16.082 billion euros, which makes 37 percent of the GDP (35.8 pct in 2017), while spending is expected to stand at 15.839 billion euros or 36.4 percent of the GDP (35.7 pct in 2017).
