This is a knock-on from the £25 congestion charge scheme for gas guzzlers and in an unpleasant twist of unfortunate injustice, a minority of motorists will find themselves not only losing their AFD but subsequently falling into the £25 bracket. A double whammy, especially if you've converted your 4 by 4 to run on LPG at considerable expense.

It's alright though, because TFL are giving you almost 2 whole years notice to allow you to change your vehicle if you're that hacked off. How thoughtful.
