VAT only accounts for between 33 and 50 % of the increase.
(And didn't I hear that some fuel tax went up when VAT was reduced ? If so how come it didn't come back off again when VAT went up ?)
I'm unsure what the global crude price has done recently, but I suspect someone is profiteering somewhere.
When you think it was "only" seventy something a litre a few years ago, difficult to believe the increase since then isn't anything more than squeezing the consumer for all that can be taken from them.
