Roman Abramovich, former Chelsea FC owner allegedly poisoned

A source close to Mr Abramovich told the BBC he had now recovered and was continuing with negotiations to try and end the war in Ukraine.

The former Chelsea football club owner has since been seen in public, being pictured at Israel’s Tel Aviv airport on 14 March.

Volodymyr Zelensky, the President of Ukraine had said Mr Abramovich had offered him help to de-escalate Russia’s invasion of the country.

The Kremlin has said Mr Abramovich played an early role in peace talks but the process was now in the hands of the two countries’ negotiating teams.
