Home secretary Theresa May said yesterday that ladies' knickers, thongs and and skimpy "Euro-style men's briefs of the type worn by adulterous Italians will be deemed low risk, while old school Y-fronts of the type that dads used to wear up until 1992 will be deemed a level one security risk and will be examined closely."
Under new laws proposed by the coalition, anyone in possession of suspicious pants could be held for up to 21 days.
The news comes after a week in which details of the underpants bomber plot continued to unfold. It was revealed that a separate attempt - to blow up a flight over New York - failed when the terrorist wore the winter underwear bought by his mother.
The blast devastated his genitalia but left everything else, including his trousers, unscathed.
Other passengers were unaware of the explosion until the bomber activated the service button and explained that there had been an explosion in his pants.
Al-Qaeda's master bomb maker Ibraham Al Asiri is believed to be creating a bomb that can penetrate any type of under garment. A CIA source told The Daily News that this would be a "game changer".
Last week, US secretary of state Hillary Clinton urged the major clothes manufacturers to start producing only very thick underwear to make it harder for bombers to execute their plan to full effect.Tweet
