MOSCOW. Oct 6 (Interfax) - Andrei Lugovoi, whom the British prosecution service, accuses of murdering Russian businessman Alexander Litvinenko should not fear the British judicial system, British Ambassador to Russian Tony Brenton said.

The ambassador said in a statement published by the Komsomolskaya Pravda newspaper on Saturday that he invites Lugovoi to come to the United Kingdom and that he will buy a ticket for Lugovoi himself, adding that an innocent person should not fear a fair trial.

Litvinenko was killed in a horrible manner which constituted a threat of radiological poisoning to hundreds of Europeans, the ambassador said. The identity of a suspect in the case was established in a thorough investigation held by the Crown Prosecution Service, he said. This is Lugovoi, Brenton said, adding that the prosecution service demanded his extradition.

Both Russia and Britain are signatories of the European convention on extradition, he said. The prosecution service provided Russian agencies with full and uncontestable evidence sufficient enough to open a criminal case against Lugovoi, Brenton said.

The case needs to be addressed at a fair and unbiased trial on the territory of the country where the crime was committed, the ambassador said. Now the UK waits for Russian authorities to scrutinize the case given to them, the British diplomat said.

It is impossible that relations between the two great powers such as Russian and the UK depend on cases similar to the Lugovoi case, he said. The two countries have to find ways to cooperate on many important international problems interaction on which could lead to a positive result, he said, adding that British authorities are ready for this. Brenton also expressed hope that Russian authorities are ready for this as well.

The British side has sought extradition of Lugovoi who is accused of murder former officers of Russian special services Litvinenko. Russia refused to extradite Lugovoi referring to the Russian Constitution. Lugovoi has stated many times that he is innocent.
