Anatoly Chubais has stepped down from his role as an international envoy for President Vladimir Putin, the most senior official to resign since Russia's invasion of Ukraine.

Russian reports said he was currently in Turkey with his wife.

Mr Chubais was given the job of coordinating Russia's sustainable development goals internationally.

After the war began he posted a picture of a murdered opposition figure, in what was seen as a critical gesture.

There was no comment to accompany his Facebook photo of Boris Nemtsov, on the anniversary of his killing in view of the Kremlin. He has also made no comment yet on his resignation.
