IT and legal services driving UK economy forward

The latest GDP data is out and it shows that the UK economy grew by 0.6% in the second quarter of the year. In June, however, the economy showed zero growth. ONS director of economic statistics Liz McKeown said: The UK economy has now grown strongly for two quarters, following the weakness we saw in the second half of last year. Growth across the three months was led by the service sector, where scientific research, the IT industry and legal services all did well."
