The UK has been accused of turning a “blind eye” to Russia’s “dirty money”, putting national security at risk.
The Commons foreign affairs committee said London was being used to hide the “corrupt assets” of President Vladimir Putin and his allies.
It said it was “business as usual” for the UK despite the poisoning of Russian ex-spy Sergei Skripal and his daughter.
This undermined the UK’s efforts to confront the full spectrum of President Putin’s offensive measures, it said.
The UK’s “lethargic response is being taken as proof that we don’t dare stop them… London’s markets are enabling the Kremlin’s efforts,” committee chairman and Conservative MP Tom Tugendhat wrote in the Sunday Times, ahead of the publication of the report.
