UK business investment dropped 0.7 per cent during the second quarter, official figures show, with Brexit uncertainty viewed by economists as a key factor.

The quarter-on-quarter tumble is revealed in the latest seasonally adjusted gross domestic product data from the Office for National Statistics, and follows a 0.5% fall in the first quarter of 2018. The latest decline meant business investment in the second quarter was 0.2% lower than in the same period of last year.

Its latest figures show UK household spending grew by 0.4% in the second quarter. UK exports fell by 2.2% during the three months to June. UK manufacturing output fell 0.7% in the second quarter. Services output rose 0.6%, and construction grew by 0.8%.
