Economists expected inflation to rise to 3.7%, though the Bank of England forecast for July inflation was 3.76%, slightly higher than consensus. Inflation in the UK has risen to an unexpected 3.8%, the Office for National Statistics says.

Ben Plowden, chief executive of lobby group Campaign for Better Transport, said: “Today’s inflation figure could mean a big fare rise for rail passengers next year, especially if the Government decides to go with an above-inflation increase like we saw this year.

Food price inflation also continues to climb, with items such as coffee, fresh orange juice, meat and chocolate seeing the biggest rises. | ITV National News
