Speak for England - J. M. Hawes

Brian Marley, a divorced Englishman, is alone in the vilest jungle on earth, about to die live on television. A contestant on Brit Pluck, Green Hell, Two Million, the ultimate reality TV show, Marley has managed to outlive his rivals and win enough money to change his life. Except that the TV crew has just been wiped out in a helicopter crash. With the crocodiles closing in, he has no option but to climb the vast cliff at his back. Inevitably, he falls...

...And awakes in a lost world that is remarkably like an Englishman's heaven. There's cricket and rugger, the Union Jack, plucky boys, pretty girls, a tough but fair headmaster - an entire miniature civilization preserved by the surviving passengers from Comet IV, which vanished in 1958.

Firmly convinced that they were the first casualties of World War III, they have kept an idyllic, pre-sixties England alive. When Brian contacts the outside world, the Headmaster is outraged to find an embattled New Labour MP unchallenged by a hapless Tory Party. With 50s conviction, he sets about restoring the values of the Eagle to England.
