Several places here in North East Wales where petrol is dearer than diesel. The worst I have seen is petrol at 104.9 and diesel at 101.9 but most are selling them at the same price or diesel just 1p dearer.
The worst news is I have a fuel card for business use and I get notified each week as to what I will get charged, this is usually on a par with the retail price but today I was informed that this week's price for diesel is 107.9. This is a sure sign of further increases. (cheapest retail is 100.9)
