Question to the Department for Transport:

To ask His Majesty's Government whether any ships of the Russian shadow fleet have entered British waters.

The UK Government monitors all vessels in UK waters which are of interest to the safety of mariners, the marine environment and the UK’s national security, and has observed suspected Russian shadow fleet vessels transiting through the UK’s territorial sea.

Since October 2024, the Department for Transport’s Voluntary Insurance Reporting Mechanism has challenged over 600 suspected shadow fleet vessels with unknown insurance, a significant portion of the shadow fleet, to provide their insurance as they transit the English Channel.
