Prince Harry will be reportedly ticked off by his army superiors for his late-night carousals and partying.
The 22-year-old will be told before he leaves for a six-month posting in Iraq next month that he must curb his drinking and behave impeccably at all times.
The warning expected to be delivered by his Commanding Officer, follows a series of undignified incidents which culminated last weekend in him falling into the gutter outside a London nightclub.
It is understood that officers in Scotland Yard's Royalty Protection Squad have also expressed concerns about Harry's penchant for drinking and nightclubs.
Privately they believe that he is becoming 'unmanageable' - putting himself at unnecessary risk of attack from fellow clubbers or even terrorists.
“Before he goes to Iraq next month, Harry will be told in no uncertain terms that his conduct has to improve. There have been concerns for quite some time about his late-night drinking - and the company he is keeping,” a source was quoted by the Daily mail, as saying.
"It is very difficult, if not impossible, for royalty protection officers to carry out their duties properly if Harry is getting drunk in nightclubs, where he may be surrounded by people who are armed or using drugs. The time has come for him grow up. He is not 18 any more he is 22," he added.
The prince is now on three weeks leave before he is sent to Iraq with the Blues and Royals.
