Marina Litvinenko: Cameron struck deal with Putin

In the Guardian, Luke Harding discusses Marina Litvinenko's reaction to David Cameron's decision to meet Vladimir Putin in Downing Street on Sunday, in the run-up to next week's G8 summit. She says it is morally wrong to "appease dictators":

Marina Litvinenko said she was convinced London and Moscow had struck a pragmatic understanding to bury the Litvinenko affair. She said: "How can you have serious talks about security in Syria with a person who doesn't want you to provide justice following a polonium terror attack in central London? It was obviously Mr Putin himself who protected Lugovoi from extradition. I believe it is Putin who also decided that Lugovoi should become a Russian MP."

From Harding's report it also emerges that the North Caucasus human rights lawyer Olga Chelysheva has been denied entry to the U.K.

Litvinenko inquest: crucial evidence to remain secret

Via the Guardian: 

The foreign secretary applied for a PII certificate on 7 February. He argued that if secret evidence were revealed it might damage "national security and/or international relations". He gave no further details.

Ben Emmerson QC, acting for Marina Litvinenko, vehemently opposed Hague's request and accused the government of a "cover-up". He said Hague and David Cameron were seeking to suppress material not for reasons of intelligence but so as not to damage Britain's trade interests with Moscow. The government, he told the hearing, was in effect "dancing to the Russian tarantella".
