Marin and Räikkönen, a businessman and former professional footballer, were married in 2020, according to Finland’s public broadcaster, YLE.
‘We have filed for divorce together. We are grateful for 19 years together and our beloved daughter,’ they wrote in separate Instagram stories.
‘We are still best friends, cool to each other and loving parents. We will continue to spend time together as a family and with each other.’
They share a five-year-old daughter together.
‘We have lived our youth together, entered adulthood together and grown into parents for our dear daughter together,’ Marin wrote on Instagram after her August 2020 wedding to Raikkonen.
The announcement comes months after Marin was criticized for partying with friends leading her to take a drug test following the backlash.
She was the first member of her family to attend university, she entered politics at 20 and quickly moved up the ranks of the center-left Social Democratic Party.
She then became the world’s youngest prime minister when she took office in 2019 at the age of 34.
Marin and her Social Democratic party lost Finland’s election for parliament last month, trailing behind the rightwing National Coalition party and the nationalist Finns party.
She is currently serving as caretaker prime minister until a new coalition government can be formed.
