So the Tories have decided to prove their eco credentials by announcing a tax on air travel. The Conservative think this can be done, apparently, by raising tax on aviation fuel.
Strangely, they seem to miss the obvious point of air travel. If you raise fuel taxes in the UK the aircraft simply fill up with fuel overseas.
According to an opinion poll this morning, 58% of electors oppose any more tax rises on air transport and as Paul Walter reminds us, 57% of Tory delegates opposed these plans at their conference.
The answer, Mr Cameron, comes from having a real all encompassing policy on the environment. Not simply raising new taxes in one area as you propose, but like the "Green Tax Switch" that the Lib Dems are offering, you give people the chance to save taxes in other areas.
This half baked Tory plans looks to all intents and purposes to be a policy designed to raise tax incomes for the treasury, not one aimed at giving consumers choice.
