Saying more than he should?

From the Conservative press release on Cameron's green speech today:

The consultation calls for submissions in response to three main policy ideas: charging fuel duty and/or VAT on domestic flights; replacing APD with a per-flight tax based more closely on actual carbon emissions; and introducing a 'Green Air Miles Allowance' so that people who fly more frequently pay tax at a higher rate

I can't see how you're going to introduce a "per-flight tax" or a "green air-miles allowance" without tracking the flights of 60 million people.

And if you're going to do that, you're going to need the e-borders scheme.

And if you're going to do that, you're going to need the national ID database up and running before you even start to consider how you're going to spend all that lovely tax revenue.

All of which makes this statement from David Davis all the more meaningless.

The Tories only have about three policies and two of them contradict.
