Inflation rose to a higher-than-expected 0.5% last month after fuel prices increased and the Euro 2016 football tournament helped drive up the cost of air fares, new figures show.
The Office for National Statistics (ONS) said Consumer Price Index (CPI) inflation in June was up from 0.3% in May and matched the 15-month high recorded in March.
CPI also came in higher than economists’ expectations of a rise to 0.4%.
Last month’s hike in the cost of living came in part from soaring flight prices, which climbed by a record 10.9% between May and June, pushed higher by more expensive air fares to Europe.
But the ONS said it was too early to see the impact on inflation of the plunge in the value of the pound triggered by Britain’s decision to leave the European Union.
ONS statistician Phil Gooding said: “The rising cost of European flights, possibly boosted by the Euro football championships, was the biggest reason for this month’s increase in inflation.
“The growing cost of oil, feeding through to petrol prices, also helped nudge up CPI.
“Today’s figures were collected before the EU referendum, so recent falls in the value of the pound will have had no impact on them.”
Overall transport prices rose by 1.1% between May and June this year, compared with an increase of 0.2% over the period in 2015, due to a hike in the cost of European flights.
A rise in the price of filling up at the pump also had an upward impact on CPI, picking up more than it did a year ago, with the cost of petrol and diesel climbing by 2.3p and 2.6p per litre respectively between May and June this year.
The price of petrol was 111p per litre in June, while the price of diesel reached 112.1p per litre last month.
The cost of recreation and culture was also up by 0.6% this year, compared with a 0.1% fall a year ago, driven in part by the rising cost of computer games.
But these price increases were offset by a slide in the cost of furniture, household equipment and maintenance, with overall prices dipping 0.3% between May and June this year.
The impact came from falling price tags for furniture, furnishings and kitchen units.
The ONS said the Retail Prices Index (RPI) - a separate measure of inflation, which includes housing costs - rose to 1.6% in June, up from 1.4% in May.
The CPI figures come amid a bleak outlook for the UK economy, with many economists slashing their growth forecasts and some pencilling in a potential recession following the Brexit vote.
