Motor fuels contributed significantly to the rise in inflation, after the average price of petrol rose by 9.1 pence per litre between July and August.
ONS chief economist Grant Fitzner said: “Sharp price rises for petrol and diesel pushed inflation up again in August.
“Higher airfares, particularly for long-haul journeys, also contributed to the increase.”
