TBILISI -- Mikheil Kavelashvili, a former soccer player and right-wing populist, has been sworn in as Georgia's new president amid a monthslong political crisis, likely further complicating the country's prospects for European Union membership.
Outgoing President Salome Zurabishvili left her residence in the presidential palace in the capital, Tbilisi, on the same day but said she remained the legitimate head of state.
The pro-Western Zurabishvili, whose term ended on December 29, had said she would not step down. She claimed her successor -- chosen by an electoral college dominated by the ruling Georgian Dream party -- is "illegitimate."
Georgia has been the scene of anti-government protests since Georgian Dream claimed victory in October parliamentary elections that were marred by instances of vote-buying, double-voting, physical violence, and intimidation.

The rallies intensified after a government decision last month to delay negotiations on the South Caucasus country joining the European Union.
In a defiant speech to thousands of supporters outside the presidential palace on December 29, Zurabishvili said she remained the "only legitimate president" and vowed to continue to fight on.
"This building was a symbol only as long as a legitimate president was sitting here," she said. "I take the legitimacy with me."
Zurabishvili, who called for new parliamentary elections, called Kavelashvili's inauguration a "parody."
Her remarks came moments after the 53-year-old Kavelashvili, a hard-line critic of the West, was formally sworn in during a ceremony in parliament.
In his speech, Kavelashvili called for the country to unite behind him around "shared values, the principles of mutual respect, and the future we should build together."
Kavelashvili has been known to make fiery anti-Western remarks in the past, although during his speech he stated that Georgians should "strengthen our country and move toward the European family."
In 2016, he helped found the People's Power party, a more-radical offshoot of Georgian Dream.
But he has remained close to the ruling party and has been criticized for his ties to Moscow-friendly billionaire Bidzina Ivanishvili, a former prime minister and founder of the Georgian Dream party,
The presidency is a largely ceremonial post, but in the current tense political environment holds deeper symbolic meaning, and the departure of Zurabishvili could deepen Georgia's split with the West -- once the nation's closest backers.
Several hundred protesters rallied outside the parliament building, with some holding up red cards in a gesture to Kavelashvili's soccer career.
The demonstrators dispersed shortly afterward but vowed to rally again in the evening.
The Interior Ministry said six protesters were detained outside the parliament building. Local media reported that several demonstrators were injured by police.
A day earlier, Zurabishvili joined protesters in Tbilisi as rally participants waved Georgian and EU flags, played music, and marched along the Saarbruecken Bridge in the capital to form a "chain of unity."

The rally marked one month since the start of the recent wave of protests, which have been met with violent police action, injuries, and mass arrests by Georgian authorities.
Protesters accuse the Georgian Dream-led government of moving the country away from the EU and tilting closer to Russia.
A U.S. State Department spokesperson on December 29 told RFE/RL in e-mailed comments that the United States is closely monitoring the situation in Georgia.
The spokeperson added that respect for the freedoms of expression and peaceful assembly are critical to a functioning society.
On December 27, the United States said it had slapped fresh sanctions on Ivanishvili for undermining Georgia's democracy for the "benefit of the Russian Federation."
"Under Ivanishvili's leadership, Georgian Dream has advanced the interests of the Kremlin by derailing Georgia’s Euro-Atlantic trajectory -- in direct contradiction to what was envisioned by the Georgian people and the Georgian Constitution," U.S. Secretary of State Antony Blinken said.
The action prompted anger from the Georgian Dream party, while the Georgian opposition hailed the action and called on the EU to also move against Ivanishvili and other Georgian leaders.
Dutch Foreign Minister Caspar Veldkamp said in an X post on December 29 that he commends Zurabishvili "for her vital leadership and unwavering commitment to Georgia's European course."
"For a month now, Georgian people are peacefully defending their democratic and European future in the streets despite violence and intimidation," he said, adding that the Georgian government should "restore public trust" and "consider possible new elections."
Zurabishvili -- who has spilt with the government and backed the protesters early in the wave of rallies -- had called on Georgian Dream to set a date for new parliamentary elections by December 29.
In another show of Western support, U.S. Republican House member Joe Wilson on December 27 wrote on X that he welcomed the new sanctions and added that he had invited Zurabishvili -- "as the only legitimate leader in Georgia" -- to Donald Trump's presidential inauguration on January 20.
Georgia received EU candidate status in December 2023, but ties with Brussels have been tense in recent months following the adoption in May of a controversial "foreign agent" law pushed through parliament by Georgian Dream, which has been in power since 2012.
