Ljubljana - The centre-left opposition has demanded convening an emergency session of the National Assembly in the wake of what they described as "a state of war" unfolding in Ljubljana yesterday, repeating their call for a snap election.

Commenting on the police using force to disperse protesters and rioters in Ljubljana on Tuesday, the Marjan Šarec List (LMŠ), Social Democrats (SD), Left and Alenka Bratušek Party (SAB) today condemned any violence in the strongest terms.

Accusing the government of intentionally creating a state of emergency, they urged its resignation as the only path to a normalisation of the situation in the country.

"We saw a state of war in Ljubljana, while Slovenia's political elite were smiling and sweet-talking in the Brdo pri Kranju castle halls," LMŠ deputy group leader Brane Golubović said, referring to the informal EU summit held at the Brdo estate yesterday.

He said an early election was needed, also to de-escalate situation, while the opposition needed to apply all democratic means in defence of democracy such as emergency sessions, deputy sessions and obstructing sessions.

"This government is responsible for the chaos in the country, for destruction, the break up of relationships between people [...] What we're seeing on the streets is terrifying," said SD leader Tanja Fajon.

She said she supported peaceful protesting and understood people's anger, disappointment and fear, urging for a snap election where people would show who had a right to run the country and in what way.

Luka Mesec, the leader of the Left, described Tuesday's scenes in Ljubljana as the lowest point of Slovenian democracy in recent years. "This government doesn't respect anything, it has shown it can rule in one way alone, that is by force," he said.

The parties thus called for an emergency session of parliament to discuss the unbearable situation in the country and the need to call a snap election.

Mesec called for resignation of Interior Minister Aleš Hojs as the one directly responsible for police violence, of Prime Minister Janez Janša and of President Borut Pahor, who is "silent as usual" when he should have sought to calm down the situation.
