MOSCOW, April 25 - RAPSI. UK experts have concluded that Russian MP Andrei Lugovoy was not involved in the death of former security service officer Alexander Litvinenko.

The experts administered a lie detector test for Lugovoy and found no evidence of his guilt, the MP told RIA Novosti on Wednesday and submitted a copy of their report.

Litvinenko fled to the UK in 2000. He died as a result of polonium-210 poisoning in London in November 2006. UK officials claimed that they had sufficient evidence to charge Lugovoy with murdering the former intelligence agent.

Earlier, Lugovoy said the charges against him were politically motivated.

Former KGB officer Dmitry Kovtun has also been accused by the UK authorities of involvement in Litvinenko's death.

Kovtun previously confirmed that Russian prosecutors had received a letter from the Crown Prosecution Service requesting his extradition to face trial. He believes the request was made under pressure from Litvinenko's wife, who is backed by self-exiled Russian oligarch Boris Berezovsky.

Kovtun was placed on the international wanted list for his involvement in the crime.

UK Ambassador to Russia Tim Barrow stated last week that the UK has not changed its position on the Litvinenko case.
