Diplomatic relations between the UK and Russia have remained under sustained strain amid ongoing disputes over the treatment and conduct of embassy staff.
The Foreign, Commonwealth & Development Office has summoned the Russian Ambassador and announced the revocation of a Russian diplomat’s accreditation.
The Foreign, Commonwealth & Development Office announced on 2 February 2026 that it has summoned the Russian Ambassador in London and revoked the accreditation of a Russian diplomat.

The Foreign, Commonwealth & Development Office said a senior official summoned the Russian Ambassador to a meeting in London. During the meeting, the UK informed Russia that it was revoking the accreditation of a Russian diplomat.

Stakeholder Comments
Ministerial Comments
FCDO spokesperson said;
“We condemn in the strongest possible terms Russia’s unprovoked and unjustified decision to expel a British diplomat last month and its baseless accusations against our staff. Summoning the Russian Ambassador, a senior FCDO official made it clear that the UK will not stand for intimidation of British Embassy staff and so we are taking reciprocal action today, revoking the accreditation of a Russian diplomat.”
“It is deeply disappointing that Russia continually seeks to disrupt the work of the UK’s diplomatic missions and deter our support for Ukraine. Any further action taken by Russia will be considered an escalation and responded to accordingly.”
Bottom Line
The UK said the revocation of a Russian diplomat’s accreditation is intended to address what it described as intimidation of British Embassy staff and follows the expulsion of a UK diplomat in Moscow.
The Foreign, Commonwealth & Development Office said the measure takes effect immediately and reflects a reciprocal approach to diplomatic actions. The government said it will continue to respond to developments in line with its stated diplomatic and foreign policy position.
