Marina Litvinenko, his widow, accused Moscow of orchestrating the murder. Though she believes the order did not come from Putin himself, she does believe it was done at the behest of the authorities, and announced that she will refuse to provide evidence to any Russian investigation out of fear that it would be misused or misrepresented. In a court hearing in London in 2015, a Scotland Yard lawyer concluded that "the evidence suggests that the only credible explanation is in one way or another the Russian state is involved in Litvinenko's murder".
