There have been calls from Welsh politicians for fuel duty to be cut in the Chancellor's Spring Statement next week. 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 Welsh Conservatives have said that a cut could help protect family budgets, but a motoring group questioned if it would be fully passed on.
