UK Military Advisor, Lt Col Joby Rimmer, says a lasting peace in Ukraine can only be provided if we step up and offer real and credible security assurances to deter Russia from further threatening European Security.

Thank you, Mr Chair. The UK strongly condemns Russia’s unprovoked and illegal war against Ukraine. We are committed to providing extensive economic, humanitarian, and defensive military assistance to Ukraine. The UK remains steadfast in supporting Ukraine’s sovereignty and security, ensuring that Russia faces consequences for its actions. Ukraine has shown it is ready and willing to work towards peace. The ball is now in Russia’s court, and President Putin must prove he is serious about peace and sign up to a ceasefire with immediate effect. The Kremlin’s procrastination and game-playing with the agreed naval ceasefire in the Black Sea, despite good faith participation from all sides, show Russian promises to be hollow.

We welcome President Trump’s readiness to increase the pressure on Russia if President Putin does not agree to a ceasefire soon. The Institute for the Study of War and others assess that Russia is using the temporary ceasefire in the Black Sea as leverage to stall efforts toward a general ceasefire and extract additional concessions from the West. This is unacceptable.

We must remain committed to the US and Ukraine’s proposal for a full and unconditional 30-day ceasefire. British, French, and Ukrainian military leaders are set to meet in the coming days to build on recent momentum in efforts to enhance Ukraine’s security. UK Prime Minister Keir Starmer has announced that the meeting aims to drive forward the next stage of detailed planning, following a call with Ukrainian President Zelenskyy. Last week in the UK’s Permanent Joint Headquarters, Britain and France led over 200 planners from ‘a group of nations politically aligned to the defence, security and sovereignty of Ukraine’. These military planning meetings have focused on how we keep the skies, the seas and the border of Ukraine safe. To be clear, a lasting peace in Ukraine can only be provided if we step up and offer real and credible security assurances to deter Russia from further threatening European Security.

And what is Russia’s contribution to peace and negotiations? We have seen no sign of Putin abandoning his war of aggression and his disregard of international law is being realised on the ground in Ukraine. Russian forces shelled a frontline settlement in Ukraine’s south-east Zaporizhzhia region, resulting in the death of a 66-year-old woman and injuries to five others. In the early hours of today, Russian attacks left 45,000 in Kherson without power, and this is despite Russia’s alleged agreement to a partial ceasefire on strikes against energy facilities following technical discussions in Riyadh in March.

The Report of the independent International Commission of Inquiry on Ukraine published on 11 March, highlighted a sharp increase in criminal cases concerning Russian troops executing wounded, captured or surrendering Ukrainian soldiers. In most situations, soldiers targeted ‘were in a vulnerable situation: unarmed, lying on the ground, kneeling, and some were partly naked’.

On 26 March, Russia convicted 23 captured Ukrainians on terrorism charges in a trial widely denounced by the international community as a sham and a gross violation of international law. The defendants received sentences ranging from 13 to 23 years in maximum security forced labour camps. The trial’s proceedings were marred by numerous irregularities and violations of fair representation. Defendants were reportedly denied access to independent legal counsel and subjected to coerced confessions obtained under duress.

Our position has not changed. We will continue to support Ukraine for as long as it takes. President Putin must stop playing games and agree to a full and immediate ceasefire without conditions. Only through a concerted and sustained effort can we hope to bring an end to this egregious campaign of violence and pave the way for a just and lasting peace. Efforts to support Ukraine and its pursuit of justice must be intensified to ensure our commitment to upholding international law and protecting human rights.

Thank you, Mr Chair.
