The Nobel Foundation announced on Thursday that ambassadors from Russia and Belarus have been invited to this year’s Nobel Prize ceremony in Stockholm after being barred from attending last year because to the Ukraine invasion.

For the first time, the foundation invited the leader of the anti-immigrant Sweden Democrats to the ceremony and separate banquet. It has regularly ignored long-serving Sweden Democrats leader Jimmie Akesson, notably in 2022 when the party finished second in parliamentary elections, claiming his party did not adhere to the awards’ values.

Five of the six Nobel prizes are awarded in Stockholm every year after a nomination process that is kept secret for the next 50 years. The Nobel Peace Prize is awarded in Oslo where separate festivities are held.

The Nobel Foundation said ambassadors from all countries that are diplomatically represented in Sweden and Norway, respectively, will be invited to the prize award ceremonies in December. Last year, the foundation left out the ambassadors of Russia and its ally Belarus.

The foundation said it sought to include even those who did not share the values of the Nobel Prize.

“It is clear that the world is increasingly divided into spheres, where dialogue between those with differing views is being reduced,” Vidar Helgesen, executive director of the Nobel Foundation, said in a statement.

“To counter this tendency, we are now broadening our invitations to celebrate and understand the Nobel Prize and the importance of free science, free culture and free, peaceful societies,” he added.

This year’s laureates will be announced in early October, while the festive awards ceremonies and subsequent banquets are set to take place on Dec. 10, the anniversary of Alfred Nobel’s death.

Sweden Democrats leader Akesson swiftly said he would not attend.

“Unfortunately I’m busy that day,” he wrote in a Facebook post commenting on the invitation.
