Prices for petrol and diesel at UK forecourts have only dipped on three days since the start of February, the latest analysis from the AA has shown.
Petrol prices have soared by 13p since the start of the month and diesel by nearly 21p - the fastest rises on record. The AA says it means that between mid-February and mid-March the cost of filling a typical 55-litre car tank leapt from £81.73 to £90.97.
The seemingly never-ending surge in prices has led to calls from Welsh politicians for fuel duty to be cut in the Chancellor's Spring Statement next week.
