More than 100,000 names have been added to a campaign to free or at least reduce the jail term handed to Taunton's Royal Marine Alexander Blackman for the murder of an Afghan insurgent.
The Taunton soldier's wife, Claire, has praised the "outstanding" backing in petitions and on social media, which includes MPs and senior military figures, saying she has been "overwhelmed".
Following his jailing last week, the 39-year-old sergeant must serve at least ten years of a life sentence after being found guilty of executing the severely wounded Taleban prisoner in Helmand in September 2011 – the first British serviceman to be convicted of murder on active service abroad since the Second World War.
Mrs Blackman's solicitor, Issy Hogg said: "She has been overwhelmed by the tremendous kindness and outstanding support which the British public has shown and would like to express her gratitude for the comfort this continues to provide."
Defence Secretary Philip Hammond said it would be "wrong" to comment on an independent judicial decision, adding: "The court will have had all the facts, including pleas in mitigation around the sentencing decision."
He added: "There may well be an appeal over the sentence."
One in three of the 900 people questioned by pollsters Survation felt he should serve no jail time at all.
Blackman's legal team has pledged to fight for a reduced sentence at the Court Martial Appeal Court and is studying whether there are grounds to challenge the conviction itself.
