Alexander Litvinenko report: The main findings of Sir Robert Owen's inquiry
Sir Robert Owen's report into the death of former Russian spy Alexander Litvinenko in London in 2006 was published on Thursday.
Here are the main findings from the report:
Mr Litvinenko ingested a fatal dose of polonium 210 while drinking tea in the Pine Bar at the Millennium Hotel on November 1, 2006
Andrei Lugovoi and Dmitri Kovtun placed the polonium 210 in the teapot with the intention of poisoning Mr Litvinenko, knowing that it was a deadly poison and intending to kill the former spy
The two men had made an earlier attempt to poison Mr Litvinenko on October 16, 2006
Lugovoi and Kovtun were acting on behalf of others when they poisoned Mr Litvinenko
There is a "strong possibility" they were acting under the direction of the Russian security service, the FSB
The FSB operation to kill Mr Litvinenko was probably approved by Russian President Vladimir Putin and Nikolai Patrushev, who was head of the FSB at the time
