[pursuant to the reply, 25 April 2007, Official Report, c.1163W]: The second paragraph of my answer stated that
“These vehicles are therefore subject to band B CO2 emissions graduated Vehicle Excise Duty. In Budget 2007 the Chancellor built on Budget 2006 changes by further reducing this rate to £35 and freezing it until 2010-11.”
My answer should have said
"These vehicles are therefore subject to the Alternative Fuel Car band B CO2 emissions graduated Vehicle Excise Duty rate. In Budget 2007 the Chancellor built on Budget 2006 changes by further reducing this rate from £30 to £15 and freezing it until 2010-11.”
I very much regret this inadvertent error.
