Speaking to LBC's Iain Dale Tom Tugendhat, the Chair of the Foreign Affairs Select Committee and Conservative MP for Tonbridge and Malling, said it was time to start sanctioning President Putin.
Earlier President Vladimir Putin's spokesman has brushed off allegations that the Kremlin was involved in poisoning the Russian leader's most determined critic, Alexei Navalny. But Mr Tugendhat told LBC that he thinks the UK should be "stiffer with the sanctions" that are in place.
Referencing the Magnitsky Act the Tory MP said sanctions should be used "more actively" to help target individuals who have been "part of Putin's mafia regime".
