Russia, Britain Air Views On Diplomatic Dispute

Zvyagintsev said the country's constitution does not allow for the extradition of Russian citizens. He said Britain's reaction to Russia's refusal to extradite Lugovoi was "legally unjustified, inadequate, and motivated solely by political reasons
that lie outside the legal realm of extradition issues."

Lugovoi is the chief suspect in the radioactive-poisoning death of
former Russian security officer Aleksandr Litvinenko, who died in
November 2006 in London.

Zvyagintsev added that "Russia has not received a single official document -- I stress, a document, not
just a piece of information -- indicating the causes of Litvinenko's death or a
document containing information about traces of the criminal use of polonium-210
found on British territory."

Meanwhile, in an interview, Britain's ambassador to Russia, Sir Anthony Brenton, challenged this view, saying that in some circumstances, the constitution is "capable of interpretation."

In his first monthly press conference as British prime minister today, Gordon Brown urged the Russian government to assume its "responsibility" and extradite Lugovoi.

It is very important that the world understands this -- that you cannot have people assassinated on British soil and then discover that you wish to arrest someone who is in another country and to be not in a position to do that," Brown said. "We cannot tolerate a situation where all the evidence is that not only was one person assassinated, but many other people were put at risk."
