Asked who she blamed for her husband's death, Marina Litvinenko told the inquiry:
I tried to be very objective and not to blame just because what I do feel and what I do believe... When the police said in fact that they blamed Lugovoy and Kovtun and they have this evidence I said, 'Yes, I agree, and I agree with this investigation.'

Alexander Litvinenko's widow and son left the Royal Courts of Justice in central London. The inquiry continues.
Marina Litvinenko told the inquiry that her husband accused Russian president Vladimir Putin of being a paedophile.
The inquiry at the Royal Courts of Justice in central London was shown a copy of the article which featured a photograph of Mr Putin and the boy and the headline 'Kremlin Paedophile'.
Giving evidence today, Mrs Litvinenko, said: "It was written in 2006 after everybody saw how Putin behaved when he met a little boy in a Kremlin tour group. He went under his t-shirt and kissed his stomach."
Robin Tam QC, counsel to the inquiry, said: "You have no idea if that allegation is true?"
Mrs Litvinenko replied: "No I have no idea."
Marina Litvinenko tells the inquiry that her husband also worked with Spanish intelligence agencies, and that he was paid once for this.
She says the work concerned organised crime, but that he didn't tell her much about it for her own safety.

Marina Litvinenko is telling the inquiry about how Alexander Litvinenko wrote articles for a website called Chechen Press after they moved to London.
She says he wrote one article entitled 'Kremlin Paedophile' which featured a photo of Russian President Vladimir Putin kissing a boy on the stomach.
She says that Boris Berezovsky funded Litvinenko's books at this time.
Marina Litvinenko is describing how she, Alexander and her son fled Russia because her husband feared for their safety.
She told the inquiry that her husband believe he would either be put in prison or killed if they remained in Russia.
Marina described how her husband approached police at Heathrow and said: "I am a former KGB officer and am looking for political asylum".
In May 2001, the family was given the option to change their names. Instead of Litvinenko, they took the name Carter.
The widow of poisoned spy Alexander Litvinenko, Marina, has been describing her late husband's relationship with the Boris Berezovsky. Marina explains how Alexander Litvinenko was assigned to monitor the Russian multimillionaire after he was the target of an assassination attempt.
Following the murder of a popular head of a TV station in 1995 there were suspicions that Berezovsky might be to blame. Litvinenko arrived at Berezovsky's office and found two police officers trying to remove him. He intervened and refused to let the officers take him away.
Marina told inquiry he was "afraid he was going to be taken somewhere and anything could happen to him. They could say he had a heart attack and a then make it easier to blame Boris Berezovsky's for this crime"
After he had prevented the security services from removing him Berezovsky was very grateful: "Boris Berezovsky said many times that Sacha had saved his life and he was very grateful," Marina told the court.
The inquiry has already heard that when Litvinenko claimed asylum in the UK Mr Berezovsky helped to finance him and his family.
