The UK says it won't comment on reports the second suspect in the Salisbury nerve agent attack is a doctor who works for Russia's military intelligence network the GRU.
He's been named by investigative website Bellingcat as Alexander Petrov.
The first suspect was named by Bellingcat last month - also as a GRU operative.
Russia denies the claims.
While the UK's not commenting on the specific identities of the two suspects, it does believe they're GRU agents who tried to kill former Russian spy Sergei Skripal and his daughter in Salisbury in March.
Former cabinet minister David Mellor believes the British government won't object to Bellingcat's naming of the men.
