Julia Hartley-Brewer has said it's only to be expected that Russian President Vladimir Putin comes after enemies like Sergei Skripal.
Our host was chatting to counter-terror expert David Lowe after Skripal, a former Russian double agent, and a female companion were left critically ill with suspected poisoning.
Skripal, a former colonel in Russia's FSB (the successor to the KGB), also worked for MI6 before being sentenced by a Russian court to 13 years in jail for high treason in 2006. Just four years later he was sent to Britain in a 'spy swap' involving former sleeper agent Anna Chapman.
Julia said the case had a lot of echoes of the saga surrounding Alexander Litvinenko, the former Russian spy who died from poisoning in November 2006.
Lowe said that the normal protocol is that "once you have a prisoner swap, that would be the end of it," and we should not expect Russian agents "committing murder in our streets."
However Julia said we shouldn't be too surprised, adding that Britain is "importing a lot of problems" from Russia in the form of gangsters and enemies of the state.
