Action over Salisbury poisonings 'unprecedented'published at 10:59 British Summer Time 21 July 2020
Kevan Jones says the expulsion of Russian diplomats following the Salisbury poisonings was "unprecedented".
It "sent a clear and strong message that actions must not be tolerated", he says.
"We must build on that momentum and that momentum must not be lost."
The poisoning with nerve agent of Sergei Skripal in Salisbury in 2018 is one of only a number of recent cases in the UK and across Europe linked to Moscow.
