THE next British government must levy a £1,000-a-head tax on private jets, the Scottish Greens demanded today.

The call came in response to Greenpeace research showing as many as 90,000 of the flights take off from the UK every year.

Analysis from campaigners at Transport & Environment has revealed the flights generate between five and 14 times more pollution than commercial aircraft, and a staggering 50 times more than trains.
