Gordon Brown has condemned reports that RAF personnel at a Cambridgeshire base were advised not to wear uniform in public for fear of verbal abuse.
He said armed forces members should be "encouraged to wear their uniform in public and have the respect and gratitude of the British people".
The decision not to wear uniform was taken by the station commander at RAF Wittering near Peterborough.
Defence minister Derek Twigg blamed "a tiny minority" for the abuse.
It has been claimed that verbal abuse has been directed at service personnel by people opposed to UK involvement in Afghanistan and Iraq.
The people responsible for the abuse, whoever they are, should be ashamed of themselves. I fully agree with Gord on this one, they shouldnt have to avoid wearing uniform for fear of abuse.
