Britain's economy picked up during a second quarter that concluded with the vote to leave the European Union, helped by the biggest upturn in industrial production since 1999.
Second-quarter gross domestic product grew by 0.6 per cent, up from 0.4 per cent in the first three months of the year, the Office for National Statistics said.
Output in the three months to June was 2.2 per cent higher than a year earlier, the strongest annual growth in a year and compared with a forecast for it to hold steady at 2.0 per cent.
But this robust pace of growth might not last into the second half of the year, given the shock to the economy resulting from the June 23 vote to leave the EU.
The improvement in economic growth in the second quarter reflected strong industrial, services and construction output in April, which largely dissipated in May and June.
