UK still burning Russian-sourced oil, new figures reveal

We see evidence that millions of barrels of Russian oil is still going into the production of energy burned by countries imposing the sanctions.

The figures were calculated by the environmental campaign group Global Witness and reviewed by BBC Verify and independent experts.

The story is reported by Newsnight’s International Correspondent Emir Nader.
