The UK Prime Minister spoke with Swedish Prime Minister Ulf Kristersson on the morning of 7 September 2026, according to a Downing Street press release issued the same day. The two leaders discussed the UK-Sweden relationship both bilaterally and through the Joint Expeditionary Force and NATO, agreeing that Russia's ongoing aggression in Ukraine and hybrid attacks in Europe underscored the value of close cooperation.

The UK Prime Minister reflected on his recent visit to Ukraine and thanked Kristersson for Sweden's strong support, particularly as Russia stepped up attacks. The leaders also discussed growth opportunities, including Rolls-Royce's delivery of Swedish Small Modular Reactors, which the UK Prime Minister cited as an example of cooperation that could create highly skilled jobs and support Sweden's plans for clean, reliable and secure power.

Finally, they discussed the UK's ambition to move closer to the European Union, with the UK Prime Minister saying he was focused on a relationship that increases security, boosts opportunity and supports growth for people in both the UK and Europe. The leaders said they looked forward to meeting soon.
