Free travel on trains. And high speed track all over the UK.
All airports to be closed.
Lorries to be banned.
Work to start immediately on a rail tunnel across the Irish Sea. Possibly via the Isle of Man.
Rail tunnel across the straights of Gibraltar (or wherever. Spain to Africa)
Rail track to be laid from Turkey through Syria, Israel and on to Cairo, and essentially round to wherever the above tunnel comes out in Morocco. Or a ferry to be provided across that end of the Med.
Basically, I'd like to be able to visit my mates in Ireland without being forced to go on Ryanair at stupid o'clock in the morning.
With the whole train-to-Africa thing, I can already get to most of Europe by train (skiiing, culture, decent wine etc) but being able to get to Egypt too would mean there's coral reefs within reach, so I'd never want to get on a plane again.
Introduction of elephants, bears, lions, tigers, kangaroos and more elephants to the New Forest. And Thetford Forest. And Fairlands Lakes (just up the road from me).
Arch to be installed as Benevolent Dictator for Life.
