My Lords, sanctions by the United Kingdom and G7 partners have cost Russia an estimated $400 billion, equivalent to four years of war funding, and contributed to a 30% fall in oil tax revenues in 2023.

The UK is investing in the Joint Maritime Security Centre to track shadow fleet activity, and we are finalising new powers to sanction individual vessels.
