Alexander Litvinenko killing suspect to testify at inquiry into death

A prime suspect in the killing of Alexander Litvinenko will be allowed to give evidence to the inquiry into the former Russian spy’s death.

Dmitri Kovtun will provide testimony by video-link after he was granted “core participant status” by the hearing’s chairman, Robert Owen.

Kovtun and Andrei Lugovoi are suspected of murdering the 43-year-old, who died nearly three weeks after consuming tea laced with polonium-210 in London in November 2006.
