‘No radiation’ at home of Putin critic Berezovsky

The 67-year-old, a former power-broker who helped Putin climb to the top of Russian politics before falling from grace, was found at his house in Ascot, 40km west of London.
Police said his death was “unexplained” and sent radioactive, biological and chemical experts to do tests in the house as they tried to piece together Berezovsky’s final hours.
