Bosnian Serb war criminal Radovan Karadzic is to serve the rest of his sentence in a British jail.
Foreign Secretary Dominic Raab said Karadzic, 75, will be moved to a UK prison from the detention centre in the Netherlands.
Karadzic was sentenced to a life sentence for the massacre of more than 7,000 Bosnian men and boys at Srebrenica.
It was described as the worst atrocity committed in Europe since the Second World War.
At was convicted at the International Criminal Tribunal in 2016 for genocide and crimes against humanity.
In a statement, Mr Raab said:
“Radovan Karadzic is one of the few people to have been found guilty of genocide.
“He was responsible for the massacre of men, women and children at the Srebrenica genocide and helped prosecute the siege of Sarajevo with its remorseless attacks on civilians.
“We should take pride in the fact that, from UK support to secure his arrest, to the prison cell he now faces, Britain has supported the 30-year pursuit of justice for these heinous crimes.”
