On Thursday, he responded to a tweet from UK Prime Minister Boris Johnson condemning the Russian government and vowing to “work with international partners to ensure justice”.
Bailey wrote: “I have so much I want to say about this tweet. But I can’t, and I won’t.”
His wife also responded to Johnson’s comments. “Justice would be fine. Deeds speak louder than words,” wrote Sarah Bailey.
“It’s been almost two and a half years since the events in Salisbury and there was no justice for Dawn and her family and no one for the Skripals, Charlie or us. And now it has happened again,” he said.
“It seems there are no consequences for the culprits. The government is right to condemn these actions, but in 2 1/2 years it will be forgotten? This is how it feels about us. #RIPDawn.”
Her partner, Charlie Rowley, was also hospitalized but was later fired. The Skripals also survived the attack.
Bailey contacted Novichok while investigating the poisoning of Skripal, a former KGB agent who ended up working for the British intelligence service. UK prosecutors said in 2018 that they had enough evidence to charge two Russians with conspiracy to murder, but did not apply for the men’s extradition because the Russian constitution did not allow it.
The Kremlin has repeatedly denied involvement in the high-profile attacks. However, Western governments, independent investigators and Russian observers see a consistent pattern of Russian state involvement in assassinations inside and outside the country.
However, US President Donald Trump – who has been widely criticized for his soft-spoken approach to Russia – has remained virtually silent on Navalny’s poisoning, and the US response on Wednesday came from a spokesman for the National Security Council.
