Police were called to the hospital where former double agent Sergei Skripal is being treated for exposure to a toxic nerve agent after a Russian TV news crew snuck in to film a report.

Officers from Wiltshire Police said they asked two men, who they believed to be news reporters, to leave Salisbury Hospital after receiving a call from security staff at just after 5am this morning.

No arrests were made, but a spokesperson for the hospital condemned the “appalling behaviour” of the Russian journalists in a statement shared by the National Union of Journalists.
