He's definitely NOT James Bond—nor even Austin Powers.And now the world's worst spy, codenamed Piglet,is facing 14 years in prison after bungling (办槽)an attempt to sell secrets to the Russians.

Aircraft engineer Ian Parr,46,tried to pass on secrets of seven sensitive projects for￡l30. 000 to a man he thought was a Russian agent called Aleksey.

But it turned out that Parr—once nicknamed "Hazard" by colleagues-actually handed over the secrets to all M15(军情五处)agent. As the father-of-two sat in the pub drinking a pint of lager to celebrate the￡25,000 he had just been given,police swooped and arrested him for spying.

But his troubles were not over. While in Belmar's Prison,he,who had given himself the codename Piglet,tried to kill himself.He wired his spectacles to the mains to try to electrocute himself-but he only succeeded in leaving an outline of his glasses bummed on to his face.

Parr had a reputation for being a bungler long before his spying exempt.

As a teenage he joined the Army,where he earned his nickname"Hazard".

An excolleague said."If you wanted a job doing,Hazard would do it badly.He blew up the barracks washing machine by overloading it."

"He was forever injuring himself when loading shells(炮弹)into the gun turret(炮塔)of the tank. I lost count of the number of times I saw him with bandages and plasters on his fingers."

"You'd hear him clanging around and there'd be a yelp and he'd squeal,'Oh,my bloody fingers.'He's very lucky to have all his fingers left."

Parr eared ￡25,000 a year at BAE(bachelor of aeronautical engineering(航空工程学士) Systems.It is thought that he tried to make money from spying because of worries about being dismissed at the firm.
