The Office for National Statistics (ONS) released its revised gross domestic product (GDP) data on Friday. The revised U.K. GDP expanded at 0.7% in the second quarter, in line with expectations and the preliminary reading, after a 0.4% rise in the first quarter.

The growth was driven by a rise in exports and business investment. Exports climbed 3.9% in the second quarter, while imports were up 0.6%.

Business investment jumped 2.9% in the second quarter.

Economists have said the increase trade might be temporary due to a stronger pound, which makes British products more expensive abroad.

On a yearly basis, the revised U.K. GDP rose 2.6% in the second quarter, in line with expectations and the preliminary reading, after a 2.9% gain in the first quarter.

The service sector climbed 0.7% in the second quarter.

Household spending rose 0.7% in the second quarter, after a 0.9% increase in the first quarter.
