Britain's economy grew in August after two consecutive months of stagnation, providing some relief to finance minister Rachel Reeves ahead of the new Labour government's first budget later this month.

Economic output rose by 0.2 percent in monthly terms in August, according to figures from the Office for National Statistics that were in line with expectations in a Reuters poll of economists.

"This will provide a timely boost for the chancellor amidst a backdrop of growing spending pressures," said Yael Selfin, chief economist at KPMG UK.

Reeves welcomed the news on Friday and said that economic growth was a top priority for the government.

All major sectors showed growth in August, the statistics office said, but weaker-than-expected growth in the dominant services sector was offset by a strong rebound in manufacturing and construction.

It left unrevised its estimates for monthly gross domestic output for July and June, when the economy stagnated, but revised down its estimates for April and May to -0.1 percent and +0.2 percent respectively, compared with previous estimates of 0.0 percent and +0.4 percent.

Sterling was little changed after the figures were released, with investors continuing to bet on a quarter-point rate cut by the Bank of England in November.

Compared to a year ago, economic output was 1 percent higher, below the 1.4 percent growth forecast by economists, a miss that reflected the downward revisions to previous months.

Britain's economy now looks on track to grow in the second half of the year, albeit at a slower rate than in the first quarter.

Last month the Bank of England said it expected economic growth to slow to 0.3 percent in the third quarter, and a similar rate of growth in the final three months of 2024.

The central bank is expected to cut borrowing costs at its Nov. 7 meeting after its first cut in more than four years in August and a pause in September.

"The big question mark is the government's vision for the economy," said Barret Kupelian, chief economist at PwC.

"For economic growth to continue on a sustained basis, businesses, households and foreign investors require certainty to make choices and investment decisions."

Prime Minister Keir Starmer will host an international investment summit on Oct. 14, aimed at boosting foreign direct investment to help improve economic growth - one of his main missions since coming to power in July.

Starmer said he was aiming for annual economic growth of 2.5 percent when campaigning in the run-up to the election - a rate Britain has not regularly reached since before the 2008 financial crash.

Britain's economy has been slower to recover from the COVID-19 pandemic than many of its Group of Seven peers, but the statistics office said the economy was 3.4 percent larger in August than it was in February 2020, before the crisis.
