"This is purely a matter of taking prudent health-and-safety precautions" said a police spokesman. "You never know when one of our officers might be caught in a conflagration in a building - perhaps, just for instance, where they may have been called upon to make an official denial - er, sorry, statement - about police matters."
"Their uniform offers only a limited amount protection. If the fire should become intense and the officer's exit were delayed, the officer could be at risk of severe injury if their underwear were flammable."
The spokesman vigorously denied that there was any other reason for the introduction of such underwear for the force. He was also in the process of denying that there had been a delay in its introduction when he was obliged to bring the press conference to abrupt halt and hurriedly leave the platform, apparently in acute discomfort, as smoke began billowing from his trousers.
