Sweden's Foreign Minister Tobias Billström has announced his resignation, citing a growing rift with Prime Minister Ulf Kristersson.

The conflict reportedly stemmed from disagreements over the NATO process and Kristersson's attempt to appoint Billström as an EU commissioner, which he declined.

Billström's departure has left the Moderates in shock, as he was a key figure in the party.

The sudden resignation has sparked speculation about his successor, with several names being considered for the role.

The new foreign minister will face significant challenges amid global uncertainties.
