Britain planning to freeze the assets of the two main Russian suspects in the death of a former Russian spy after a judge's report that also points the finger at Russia's president.

Details from FOX's Simon Owen in London:

Vladimir Putin implicated in the murder of Alexander Litvinenko, who died here in London in 2006, after his tea was laced with a radioactive isotope.

A public inquiry concluding that Putin probably approved the assassination plan:

(Cameron) "What happened was absolutely appalling."

British Prime Minister David Cameron... But Russia pushing back, rejecting the report as politically-motivated.

The Russian Ambassador to the UK saying:

(Yakovenko) "For us, it's absolutely unacceptable that the report concludes that the Russian state was involved in any way in the death of Litvinenko."

Ambassador Alexander Yakovenko saying Russia-UK relations will now suffer.
