To ask His Majesty's Government what steps, beyond expressions of support, they have taken to help to establish an international tribunal that would try those in Russia responsible for serious crimes under international humanitarian law, and what obstacles they have identified in doing so.

The UK is committed to holding Russia to account for its actions in Ukraine. We are actively engaging in the Core Group established by Ukraine to explore options for a Special Tribunal on the Crime of Aggression, including on the form any tribunal might take. We support exploring the creation of an internationalised tribunal, rooted in Ukraine's jurisdiction but with international elements. The creation of a special tribunal requires both establishing a sound legal basis and securing broad international support.
