Some supermarkets have been charging drivers 6p more per litre of fuel, costing motorists nearly £1 billion last year, a government watchdog has found.

In response to these findings, the Government said it will look to introduce a new law forcing fuel retailers to make real-time pricing information available to all drivers.

But until then, you can find out the unleaded petrol and diesel prices in Wrexham by using the PetrolPrices app.
