More than two-thirds of London's employers are likely to vote to stay in the EU, according to new research from online employment platform Reed.
In a survey of 1,700 employers across the UK, 71 per cent of those based in London said they would vote remain when the referendum polls open on 23 June, while 61 per cent of employers back the remain campaign across the country.
Reed's survey found the region with the fewest remain supporters was the south east of England, with just over half (52 per cent) saying they would back the remain campaign.
Almost two in three London employers (62 per cent) believe a Brexit would put UK jobs at risk.
Overall more than half of employers fear leaving Europe could put jobs at risk, while 55 per cent believe Brexit will deter foreign investment in the UK.
When asked if an EU exit would lead to more jobs for UK workers, 63 per cent of respondents said no.
For those in the remain camp, the economy (48 per cent) and business and trade (41 per cent) are the two biggest issues driving their decision for Britain to stay in the EU.
On the other hand, for those voting to leave in the June poll, British sovereignty (51 per cent) and immigration (32 per cent) are the driving factors.
James Reed, chairman of Reed, said:
We surveyed over 1,700 employers and they are very clear; a strong majority said that we should remain in the EU. And it’s easy to understand why. More than half of UK employers think jobs would be at risk if the UK leaves the EU. And for many people, this is the harsh reality that could affect them most.
