I can today tell the House that, based on a body of intelligence, the government has concluded that the two individuals named by the police and CPS are officers from the Russian Military Intelligence Service. Also known as the GRU. The GRU is a highly disciplined organization with a well-established chain of command.
So this was not a rogue operation. It was almost certainly also approved outside the GRU at a senior level of the Russian state. We have obtained a European arrest warrant and will shortly issue an Interpol red notice. Of course, Russia has repeatedly refused to allow its nationals to stand trial overseas, citing a bar on extradition in its constitution.
So as we found following the murder of Alexander Litvinenko, any formal extradition request in this case would be futile. But should either of these individuals ever again travel outside Russia, we will take every possible step to detain them, to extradite them, and to bring them to face justice here in the United Kingdom.
