UK inflation unexpectedly accelerated to a six-month high in August, boosted by the cost of theatre shows, computer games, transport fares and clothing.
Annual consumer-price growth quickened to 2.7% from 2.5% in July, the Office for National Statistics said on Wednesday. The median forecast in a Bloomberg survey was 2.4%.

The pound jumped 0.5% to $1.3208 after the data.
