THE SUN: PRINCE Harry is back on the cigs, The Sun can reveal.
The royal soldier, 26, tried to give up after his ten-week stint in Afghanistan in 2008.
But he has been seen smoking again and took his favourite Marlboro Golds on his Walking with the Wounded North Pole challenge.
A source said: "Harry has really battled with fags, but he doesn't seem able to give up once and for all.
"One reason he smokes is boredom. He's been learning to fly helicopters - which is great when you're flying but there's a lot of sitting around, doing nothing.
"Harry has been training hard for his ice trek, but that hasn't stopped him puffing away.
"If he wants to give up, he's clearly got a challenge on his hands." » | Duncan Larcombe, Royal Editor and Richard White | Monday, April 04, 2011
