Downing Street has confirmed that the Prime Minister, Sir Keir Starmer, spoke with US President Donald Trump on 5 February 2026. The official note lists two priorities: Ukraine peace negotiations and the bilateral deal securing the joint UK–US base on Diego Garcia. (gov.uk)
On Ukraine, No 10 recorded the Prime Minister’s deep concern about continued Russian attacks on civilians amid sub‑zero conditions. The leaders reviewed the state of the peace talks, with the UK restating support for Ukraine while diplomacy continues. (gov.uk)
On basing, both leaders endorsed the importance of the Diego Garcia arrangement and said the UK and US would keep working closely on implementation. The Ministry of Defence has previously described the 22 May 2025 agreement with Mauritius as securing the base’s long‑term future within the UK–US defence partnership. (gov.uk)
Legislative follow‑through is under way. According to UK Parliament, the Diego Garcia Military Base and British Indian Ocean Territory Bill, which implements provisions of the 2025 UK–Mauritius treaty including arrangements for the joint base, returned to the House of Lords for consideration of Commons amendments in January 2026.

The latest call followed a 3 February exchange in which No 10 highlighted Russian strikes on energy infrastructure and temperatures below –20°C. Read together, the two readouts point to leader‑level alignment on maintaining pressure on Russia while backing ongoing talks. (gov.uk)
For departments and partners, the message is continuity: sustained support to Ukraine alongside diplomacy, and steady delivery of the Diego Garcia framework. The 5 February note did not set new timelines, conditions or additional operational detail. (gov.uk)
The call also fits a pattern of regular leader‑level contact since December, including readouts on 21 December 2025, 8 January 2026 and 24 January 2026. That cadence suggests working‑level coordination will continue between the FCDO and MOD as implementation proceeds. (gov.uk)
Analysis: The 5 February readout is a status check rather than a policy announcement. Watch for progress on the Diego Garcia bill through ‘ping pong’ and any joint statements from the Ukraine talks as the clearest indicators of delivery pace.
