Despite there being no palpable evidence as yet, Britain is convinced that there’s more to the poisoning of Alexei Navalny. Foreign Secretary Dominic Raab on Wednesday alleged that Russia owed them answers, during a speech in Washington. Raab also averred that “the use of a chemical weapon was unacceptable.”

“The Russian government is duty-bound to explain what happened to Mr. Navalny,” said Raab, during the speech alongside Mike Pompeo. “From the UK’s point of view, very difficult to see any plausible alternative explanation to this being carried out by the Russian intelligence services, but certainly the Russian government has a case to answer,” he added.

Navalny’s speedy recovery was welcome, as the anti-corruption activist shared pictures from his bed at the Charite Hospital in Berlin on Tuesday. The photograph testified him recuperating well after he has collapsed on flight post a poisoning episode in Siberia, last month. Hospital reports indicated that the politician cum activist was poisoned with a Novichok nerve agent.

The picture was shared on Instagram via a post, on which Navalny announced that he was breathing free of ventilation. The post read: “Hi, this is Navalny. I have been missing you. I still can't do much, but yesterday I managed to breathe on my own for the entire day. Just on my own, no extra help, not even a valve in my throat. I liked it very much. It's a remarkable process that is underestimated by many. Strongly recommended.”

The Russian opposition figure is set to return to Russia upon complete recovery, suggested his spokesperson Kira Yarmysh. “It's puzzling to me why anyone should think otherwise,” she tweeted, soon after Navalny posted on Instagram.

Speculations ran amok as soon as Navalny’s poisoning surfaced as he felt violently sick while campaigning on Aug. 20, and was airlift via emergency to Berlin. While Moscow has time and again refused the allegations, while The Kremlin termed them groundless; it has been reported that laboratory tests in three countries have determined he was poisoned with a Novichok nerve agent -- his teams alleged that the poisoning wasn’t accidental, and was rather carried out on the orders of Russian President Vladimir Putin.
