No. 10 Downing Street reported on 27 January 2026 that Prime Minister Keir Starmer spoke with Sweden’s Prime Minister Ulf Kristersson. The UK thanked Sweden for its consistent support to Ukraine and highlighted the need to go further on resilience, energy security and air defence. Both leaders stressed long‑term security assurances and continued international backing for a just, lasting peace. They also noted the strength of UK–Sweden defence ties and agreed on the need to step up security in the High North and across Europe to deter threats from Russia, with a plan to speak again soon.

The discussion reflects a relationship that has been formalised in recent years. The two governments signed a Strategic Partnership in October 2023, deepening cooperation on security, counter‑terrorism and defence exports. This builds on a UK–Sweden Political Declaration of Solidarity from May 2022, which envisages mutual assistance, upon request, in the event of crisis or attack. (gov.uk)
Sweden’s place inside NATO further aligns London and Stockholm. Sweden became the Alliance’s 32nd member on 7 March 2024, which NATO said makes the Alliance stronger and Sweden safer. This embeds UK–Sweden coordination within Alliance planning, alongside activity by the UK‑led Joint Expeditionary Force across the High North, the North Atlantic and the Baltic Sea. (nato.int)
References to long‑term assurances match existing frameworks. G7 leaders issued a Joint Declaration at Vilnius in July 2023 to provide enduring military, economic and industrial support to Ukraine. The UK concluded a ten‑year UK–Ukraine Agreement on Security Co‑operation on 12 January 2024, followed by a broader One Hundred Year Partnership in January 2025 that acknowledges the 2024 agreement.

No. 10’s readout concentrates on two operational priorities: air defence and energy resilience for Ukraine. Delivery sits within G7 commitments and bilateral arrangements with Ukraine to provide capabilities, training and industrial support, which frame how the UK and partners coordinate assistance.

The emphasis on the High North aligns with published UK policy. The Ministry of Defence’s 2022 paper on the UK’s Defence Contribution in the High North and the 2023 Arctic framework Looking North set priorities to protect critical national infrastructure, uphold freedom of navigation and maintain a credible presence with partners, including through NATO and the JEF. The 2023 Integrated Review refresh also noted intensifying competition in the region. (gov.uk)
JEF leaders have already set out their theatre. Meeting in Visby in October 2023, they underscored that Russia is the most significant and direct threat to Euro‑Atlantic peace and stability and identified the High North, North Atlantic and Baltic Sea as their focus. The JEF complements NATO and enables rapid sub‑regional coordination when required. (government.se)
Overall, the readout signals continuity: UK–Sweden alignment inside NATO, continued backing for Ukraine under long‑term assurance frameworks, and sustained priority on the High North. Detailed measures typically follow through departmental updates and NATO communiqués. (gov.uk)
