Naomi Long MP said: “The Allies fought bravely during World War Two to rid Europe of the Nazis, so to see this salute in front of a Union flag is not only sickening but a dishonour to both the flag and the uniform they are wearing.
“It is completely unacceptable for anyone to glorify fascism. The genocides carried out by the Nazis underline how disgraceful this photo is.
“It has been reported that the two soldiers involved have been disciplined by their superiors. I hope that appropriate action will be taken to underline the seriousness of their offence.”
