Traces of radioactive polonium-210 have been found at the offices of an associate of poisoned ex-KGB spy Alexander Litvinenko. Two addresses in London’s Mayfair are being examined, including that of Russian exile Boris Berezovsky. Billionaire Berezovsky had regular dealings with Litvinenko, who visited the offices near Hyde Park “almost every day”, according to one source.
Berezovsky was given political asylum in London in 2001 after charges of fraud and corruption in Moscow. He is a strong critic of the Kremlin. Polonium-210 has been found in at least five locations across London, from Litvinenko’s home in Muswell Hill in the north, to Piccadilly in the centre.
