Britain's economy accelerated in the second quarter on the back of strong consumer spending, although the economy remains fragile and vulnerable to weak trade and business investment. The Office for National Statistics said the domestic economy expanded 0.7% between the first and second quarters, unrevised from the previous estimate. On an annual basis growth, however, it was revised down to 1.3% from 1.5% due to general government revisions. Figures also showed the nation's industrial production was upwardly revised to 0.8% from 0.6%, while manufacturing activity expanded 0.9%- the fastest rate since Q3 2010. Furthermore, construction and services sectors also gained momentum during the period.
