An error in car tax data provided by the British government has led to a minor overstatement of the country's consumer price inflation rate, according to a recent announcement by the Office for National Statistics (ONS).

The miscalculation, related to vehicles subject to Vehicle Excise Duty, resulted in a 0.1 percentage point inflation rate overstatement for the year up to April. The ONS noted that the consumer price inflation rate was reported at 3.5% in April, a rise from March's 2.6%.

Although the Consumer Price Index won't be revised, the ONS stated it would rectify future data calculations and reassess the quality assurance processes for external information. The British government has initiated an investigation into the accuracy of official economic data amid growing criticism.
