The murder of ex-Russian spy Alexander Litvinenko in 2006 was “probably” approved by President Vladimir Putin, a public inquiry has concluded.
Mr Litvinenko died aged 43 in London days after being poisoned with radioactive polonium-210, which he is believed to have drunk in a cup of tea.
Chairman Sir Robert Owen said it was likely Mr Putin signed off the killing following a long-running feud.
Two Russian men, Andrei Lugovoi and Dmitry Kovtun, have been accused of Mr Litvinenko’s murder. They both deny killing him.
Sir Robert said the two suspects were probably acting under the direction of Moscow’s FSB intelligence service.
