Official figures from the Office for National Statistics showed the economy expanded by 0.1% in August against expectations of a small decline, and by 0.7% in the three months to August. Healey told the BBC the result was "a sign of resilience in the UK economy that some had not expected," adding that "it's really tough in the face of these economic global shocks."
The growth was driven by increased production, including manufacturing, oil and gas extraction and energy supply. The services sector, the largest part of the UK economy, was flat during the month, while construction contracted.
The figures follow an upgrade to this year's forecast for the UK economy from the International Monetary Fund earlier this week. Healey said the growth reflected "part of the discipline the IMF here in Bangkok this week has endorsed that they see in Britain."
Ahead of his first Budget, due in two weeks, Healey said he wanted "to give people a bit of breathing space from the cost of living and cost of business pressures." He did not detail specific measures, saying "where we can take action, we will," but insisted the government would maintain fiscal discipline: "where we want to do things we have to make sure we can pay for them within the Budget that we've got and control spending."
