Martin Sandbu, European economics commentator at the Financial Times, discusses the challenges and opportunities involved in using Russia's currently frozen Central Bank assets to support Ukraine's economy and reconstruction.

The hashtag 'Russia Must Pay' is frequently trending on social media, boosted by politicians, civil society organisations and individuals outraged by Russia's continued aggression. But while this sentiment is easy for politicians and financiers to articulate, it has yet to be matched in deeds. Martin Sandbu joins host Tom Keatinge to explore how the $300 billion of immobilised Russian Central Bank assets could be unlocked and deployed to support the Ukrainian economy and fund the huge costs associated with the reconstruction of a country devastated by Russia's illegal war.
