MOSCOW, April 3 - RAPSI. The late oligarch Boris Berezovsky, who was found dead on March 23, planned to give testimony regarding the death of former security agent

Alexander Litvinenko, State Duma Deputy Andrei Lugovoi told RIA Novosti on Wednesday.

"He indeed planned to testify in court in London, and that is absolutely certain," Lugovoi, a member of the Liberal-Democratic Party and the head of the State Duma Security and Anti-Corruption Committee, said.

Berezovsky was found dead in the bathroom of his Berkshire house on March 23. He was once one of Russia's wealthiest men.

The British authorities have accused Lugovoi of involvement in the murder of Litvinenko, who fled to the UK. Lugovoi has dismissed the accusations as politically motivated. He recently suggested that Berezovsky was involved in the murder, as he kept in touch with Litvineko and sponsored him financially.
