UKIP Veterans Spokesman, Mike Hookem MEP, has blasted a decision by judges not to release Sgt. Alex Blackman on bail saying, "its an absolute disgrace."
Sgt. Alexander Blackman - known as Marine A - is currently serving a sentence for murder following the killing of a fatally wounded Taliban fighter in Afghanistan in 2011.
However, in a court ruling last week, the Royal Marine was given leave to appeal his conviction after his defence team offered new evidence.
Speaking of a judge's decision to deny bail pending the appeal, former soldier Mr Hookem said: "It is an absolute disgrace that a man who served his country so well, and who poses no risk to the public is denied the opportunity to spend Christmas with his family.
"I think many people in the veterans community will be absolutely appalled at the treatment of Sgt Blackman and rightly so.
"This is a man who deserves treatment, not prison. To me, this smacks of a political decision overriding common sense.
"I also feel for Mr Blackman's family who I know would have been looking forward to welcoming him home.
"For me and the rest of the veteran community fighting on Mr Blackman's behalf, the struggle will go on until he is back in the arms of his family and receiving the treatment he needs, rather than remaining in prison.
"I now look forward to Mr Blackman's next day in court, where he can once again try to clear his name."
Peter Jewell, UKIP's Justice spokesman added: "UKIP supports the bail application, we believe that there is a fine line of acceptance in the actions of the military under fire and that we have to support the brave men and women of our armed forces.
"There is no likelihood of Sgt Blackman re-offending, nor is there any likelihood of him interfering with witnesses, nor is he likely to fail to answer his bail. He should be home with his family this Christmas."
