The UK Prime Minister spoke with Finnish President Alexander Stubb on the night of 21 October 2026, according to a Downing Street account published the following day. The two leaders discussed international backing for Ukraine and the goal of a just and lasting peace, agreeing on the importance of maintaining momentum to end Russia's attacks.

According to the account, both agreed that any peace must include security guarantees for Ukraine and ensure war does not return to the European continent. Stubb opened the call by reflecting on events in Oslo over the preceding 48 hours.

The Prime Minister also set out his vision for next month's UK-EU Summit and thanked Stubb for Finland's support for closer UK ties with the European Union. The leaders agreed to remain in close contact in the coming days.
