We are ending our live coverage of reaction to the conclusions of the Litvinenko Inquiry here.
We leave you with a recap of the main events of the day.
- Judge Sir Robert Owen's report on the death of former Russian spy Alexander Litvinenko in London in 2006 concludes that Russian President Vladimir Putin "probably" approved his murder
- The long-awaited report found two Russian men - Andrei Lugovoi and Dmitry Kovtun - deliberately poisoned Mr Litvinenko by putting radioactive polonium-210 into his tea at a hotel
- Mr Putin is likely to have signed off the poisoning in part due to personal "antagonism" between the pair, as well as because of his work for British intelligence agencies, criticism of Russian authorities, and association with other Russian dissidents, the report says.
- David Cameron promises the UK is "toughening" its action against Russia. He says UK will have to continue "some sort of relationship with them [Russia]" but with "clear eyes and a very cold heart"
- Russian Foreign Ministry reacts to the inquiry calling it "politicised" and saying it has "overshadowed the general atmosphere of bilateral relations"
- Mr Putin's spokesman says Moscow's official response will happen through "diplomatic channels". Mr Putin himself has not commented,
- Home Secretary Theresa May faces criticisms from all parties in the Commons, including calls from Labour for the 2018 Fifa World Cup to be taken away from Russia
- Widow Marina Litvinenko says she is "very pleased" with the report and calls for a UK government travel ban for Mr Putin and sanctions against Russia
- Russian suspect Andrei Lugovoi calls the allegations against him "absurd", while his fellow suspect Dmitry Kovtun says he will react once he has more information about the report findings
