We were pondering the ramifications of the Liberal Democrats' latest environmental policy and generally bemoaning the idiocy of politicians when a glimmer of hope hit us.
You see, in order to make this scheme pay the Lib Dems would need the maximum amount of revenue possible. So in actual fact it would be in their interest for the number of trucks on the road to actually increase, thus giving them more money to spend on the railways.
So Lib Dems = pro road freight.
Should they ever get into power remind them of this fact when they have £1.50 of extra funding to put into the railways.
