Vladimir Putin should be held responsible for the murder of Alexander Litvinenko, the inquiry into the Russian spy's death was told as six months of hearings came to an end.

It would be "impossible" for such an "assassination" to happen without the approval of the "morally deranged" Russian president, counsel for the Litvinenko family told the inquiry.
