Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what assessment he has made of the potential implications for his policies of alleged reports that Russia has used chemical weapons in Ukraine .

The Ministry of Defence continues to assess and monitor the evolving threat picture in Ukraine, including illegal Russian use of chemicals as a method of warfare. Russia has publicly admitted to the use of Riot Control Agents (RCAs) on the battlefield against Ukraine, and there are multiple reports of the use of the toxic choking agent chloropicrin. In December last year, a Technical Report confirming the use of Riot Control Agents in Ukraine was published by the Organisation for the Prohibition of Chemical Weapons.

The UK has been at the forefront of international support and assistance to Ukraine and has previously provided respirators and decontamination kits to the Armed Forces of Ukraine, as well as other protective measures to enhance Ukraine’s protective capabilities against chemical weapons. In December 2024, following a direct request for UK Assistance by Ukraine, the Ministry of Defence announced a further assistance package including funding for the procurement of respirators and other equipment to protect Ukraine's forces. This is being procured jointly with international partners through the G7 led Global Partnership Against the Spread of Weapons of Mass Destruction.

Our commitment to Ukraine is unwavering and we continue to work closely with our international partners, both bilaterally and in multilateral forums, to coordinate counter-CBRN support and assistance to Ukraine.
