Iceland's president holds a largely ceremonial position in the parliamentary republic, acting as a guarantor of the constitution and national unity.
He or she does however have the power to veto legislation or submit it to areferendum.

Jakobsdottir, who served as the head of a left-right coalition governmentfrom 2017 until April when she stepped down to run for president, has had tofend off criticism that she is too political for the job.
"I actually think that knowing the political environment doesn't make youless qualified to handle the job of president," the 48-year-old said Thursdayduring a televised debate, when asked if her political career would be ahindrance for her as president.
"On the contrary... I believe that I can rise above all party politics," shesaid.
The televised debate saw the candidates trade barbs on topics ranging fromthe country's NATO membership, weapons for Ukraine, the possible sale ofIceland's national power company and the use of presidential veto powers.
