MOSCOW, August 29 (RIA Novosti) - Andrei Lugovoi, the U.K.'s key suspect in the murder of Alexander Litvinenko, said Wednesday he would not go to Britain as his situation has become too politicized.

"I am not going anywhere because this [murder] case involves big politics," Lugovoi told a news conference. "I propose that if the British justice authorities have any proof, that they send it here, to Russia."

The former KGB officer added he was sure that British intelligence was involved in the murder of Litvinenko last November in London.
