Thousands of Georgians protested in the capital Tbilisi as a new president allied with the ruling Georgian Dream party was inaugurated.
Mikheil Kavelashvili, a former pro footballer, has been sworn in during a critical political period for the country after the government suspended its application to join the European Union.
Georgian Dream won parliamentary elections in October, but the victory was mired in allegations of fraud which have since sparked several street protests.
Outgoing president Salome Zourabichvili refused to step down on Sunday, saying she was the “only legitimate president”.
Addressing crowds gathered outside, Zourabichvili said she would leave the presidential palace but branded her successor illegitimate.
“This building was a symbol only as long as a legitimate president was sitting here,” she said.
A few minutes’ walk away, Kavelashvili was sworn in at a closed-doors ceremony in parliament, where he was accompanied by his family. Prime Minister Irakli Kobakhidze also attended the inauguration.
Speaking after taking the oath, Kavelashvili went on to praise Georgian “traditions, values, national identity, the sanctity of the family, and faith”.
“Our history clearly shows that, after countless struggles to defend our homeland and traditions, peace has always been one of the main goals and values for the Georgian people,” he said.
Kavelashvili is a former MP with the Georgian Dream party and was the only candidate for the job. Zourabichvili has previously denounced his election as a travesty.
Georgian Dream has become increasingly authoritarian in recent years, passing Russian-style laws targeting media and non-government groups who receive foreign funding, and the LGBT community.
