The UK tech sector has delivered its verdict on the EU referendum, with a new survey showing overwhelming support for Britain retaining its membership.

Only 4% of respondents said they would vote for Britain to leave the EU, with 9.49% saying they were undecided.

The survey from Tech London Advocates comes as the independent private sector network launches its TLA EU-Yes working group, which will bring together members of London’s tech sector to highlight what it sees as the risks for tech of Britain leaving the EU.

The group says that in the case of a "Brexit" London’s access to talent, influence in regulatory decisions, access to trade agreements, ability to attract global HQs to the UK, and collaboration with other European digital hubs would all diminish.

Russ Shaw, founder of Tech London Advocates, said, "We asked members of London’s digital community whether they felt Brexit would accelerate or damage growth in the capital.

The overwhelming response has given us a clear mandate to call for a Yes response on behalf of tech professionals in the digital capital of Europe.

"Every challenge the capital faces in its efforts to remain a centre for digital excellence will be exacerbated by withdrawal from the European Union."

Ghislaine Boddington, founder of body>data>space, said: "Without clarifying the benefits of the EU on our digital community, we risk sleepwalking into a disaster for the future growth of our industry, as we will loose imperative collaborations, knowledge transfers and marketplace exchanges."

The group surveyed 292 members.
