Question to the Ministry of Defence:

To ask the Secretary of State for Defence, pursuant to the Answer of 3 June 2026 to Question 759 on Russia: Shipping, whether there has been an increase or decrease in the number of vessels transiting UK waters since his Department's press release entitled Shadow fleet set to be interdicted in UK waters in latest blow to Russia, published on 25th of March 2026.

The Royal Navy with the Joint Maritime Security Centre keeps maritime activity in UK waters under constant review. Any enforcement action is considered on a case‑by‑case basis, in accordance with international law and domestic legislation.

We will not provide a running commentary or get into details of our decision-making process as this could compromise our ability to successfully take action against sanctioned ships, only benefitting our adversaries.
