The Labour leader Ed Miliband has said he does not believe the conviction of a Royal Marine for the murder of an Afghan insurgent has diminished the reputation of the armed forces.
He said: "When any incident like that happens, it is tragic and it must be dealt with.
"But what is really important is to know and to realise what our armed forces are and who our armed forces are and they are brave, decent, honourable people who do the right thing for our country."
"I think that's what the British people know....it doesn't change the esteem in which our armed forces are held.
A commando in the Royal Marines has been convicted of the killing of a seriously injured Afghan fighter, described as "an execution".
Still images and audio recordings of three Royal Marines allegedly murdering a captured Afghan man in 2011 have been released.
