Radio Times' bosses have issued an apology after the current issue accidentally included an indecent photograph.
The 28 January - 3 February issue of the listings magazine, that has just been published, features a photograph of a group of Royal Marines in which one Marine is exposing a part of his anatomy.
The magazine's staff failed to notice the rogue body part, which was in an image promoting a new Channel 5 documentary series.
However, eagle-eyed readers were quick to point out the error with one writing: "I know that British soldiers serving in Afghanistan are well equipped, but seeing the roll call of Royal Marines gives the expression a whole new meaning.”

An apology on radiotimes.com said: "It has come to our attention that an apparently innocent photo of the Royal Marines’ 42 Commando unit – printed by Radio Times in good faith and issued by Channel 5’s publicity department to promote the documentary 'Royal Marines: Mission Afghanistan' – contains the sight of one of the marines playing a prank.
"What we took to be the marine’s finger proved, on closer inspection, to be another part of his anatomy."
The magazine's editor Ben Preston added: "We apologise for any upset caused to readers by the rogue member of 42 Commando.”
