Question to the Ministry of Defence:

To ask the Secretary of State for Defence, how many Russian-sanctioned vessels transiting UK waters have changed flag mid-voyage prior to entering UK waters since 24 March 2026.

The Ministry of Defence continually monitors all activity within UK waters. We will not provide details on the numbers of vessels or our decision-making process as this could compromise our ability to successfully take action against sanctioned ships, only benefitting our adversaries.
