The news comes as a major boost to Britain’s technology sector. Sundar Pichai, the Chief Executive of Google, told the BBC that the UK was still an attractive place to do business.
He said open borders and free movement for skilled migrants were “absolutely” important to the success of the technology sector in the UK.
It was Pichai’s first European broadcast interview since he became chief executive last year.
Sources at the technology company also said if barriers were thrown up to skilled immigration following the vote to leave the European Union, some of Google’s investment could be at risk. At present, Google employs around 4,000 people in the UK, a figure that could now rise to 7,000.
