The government won't make any more profit in the long run, only the petrol stations that have hiked their prices will and then it's only off the fools brimming their tanks now.
W/E happens I don't care, I can work from home so won't loose out and it's actually a blessing working at home
EDIT: My wife the "Wallingford ESSO Petrol & Diesel price spotter" said the diesel price has gone down from 147.9 to 146.9 so there ya go, the local Scott who runs the station isn't ripping us off
