And in a statement released by the Foreign Office, Mr Hague added: "This landmark verdict demonstrates that those who have committed the most serious of crimes can and will be held to account for their actions.
"It demonstrates that the reach of international law is long and not time limited and it demonstrates that heads of state cannot hide behind immunity.
"The verdict can only be a small comfort for the victims and relatives of those killed. But the Court's authoritative view of what occurred will play an important role in helping the people of Sierra Leone come to terms with the past and consolidate national reconciliation."
