Poisoned spy visited Israel with oil dossier

A dossier drawn up by Alexander Litvinenko on the Kremlin’s takeover of the world’s richest energy giant will be given to Scotland Yard today as police investigate the former KGB spy’s secret dealings with some of Russia’s richest men.

It emerged yesterday that Mr Litvinenko travelled to Israel just weeks before he died to hand over evidence to a Russian billionaire of how agents working for President Putin dealt with his enemies running the Yukos oil company.

He passed this information to Leonid Nevzlin, the former second-in-command of Yukos, who fled to Tel Aviv in fear for his life after the Kremlin seized and then sold off the $40 billion (£21 billion) company.
