"A decision has been taken by the president (of the court) that he will serve his sentence in the UK," tribunal spokesman Jim Landale told a news conference on Wednesday.
The Bosnian Serb general was originally convicted of genocide in the 1995 Srebrenica massacre, Europe's worst atrocity since World War Two, and given a 46-year jail term. He, however, had his jail sentence cut to 35 years by the appeals chamber at The Hague war crimes tribunal on 19 April this year when it convicted him of aiding and abetting the crime.
According to the final verdict, the Bosnian Serb Army committed an act of genocide in Srebrenica between July 12 and 19, 1995, when it executed more than 7,000 Muslim men and boys. The killings became one of the most notorious episodes of the 1992-95 Bosnian war.
In 2003, the ICTY signed an agreement with Great Britain on offering prison space to the tribunal. The ICTY has signed similar agreement with Finland, Sweden, Norway, Danmark, Germany, Austria, France, Italy and Spain.
