Greece’s ruling New Democracy party scored a crushing victory in parliamentary elections Sunday but fell short of winning an outright majority in a vote dominated by the cost-of-living crisis, a wiretapping scandal and anger over the country’s deadliest-ever train crash, writes CNN.

With more than 99% of votes counted, ruling center-right party of Prime Minister Kyriakos Mitsotakis, surpassed all expectations garnering more than 40% of the vote in a result he described as a “political earthquake”.

His main opposition, Alexis Tsipras’s centre-left Syriza party, suffered major losses, coming in second with just over 20% of the vote.

However, Mitsotakis did not win enough votes to secure a single-party government. The vote was held under a new proportional representation system that requires a threshold of around 45%.

Greek President Katerina Sakellaropoulou will now give the top three parties up to three days to form a coalition, though Mitsotakis has already indicated he’s not interested in sharing power.

“Without a doubt, the political earthquake that occurred today calls on us all to speed up the process for a definitive government solution so our country can have an experienced hand at its helm as soon as possible,” Mitsotakis told jubilant New Democracy supporters massed outside party headquarters in Athens.
