Alexander Petrov and Ruslan Boshirov, who are wanted for the Skripal novichok attack, are linked to Russian defence ministry
Documents uncovered by investigative journalists have provided the first public evidence that the suspects in the Salisbury novichok attack have formal ties to the Russian ministry of defence.
British authorities have charged Alexander Petrov and Ruslan Boshirov with conspiracy to murder Sergei and Yulia Skripal and Detective Sergeant Nick Bailey. The former Russian spy and his daughter were found collapsed on 4 March; the police officer fell ill after trying to help them. Prosecutors say Petrov and Boshirov work for Russian military intelligence, which President Vladimir Putin has denied.
