Polls have closed in the United Kingdom, and the “Remain” side in the country’s contentious “Brexit” referendum that will decide whether Britain will stay in the European Union appears to have the edge. Polling results published by British-based market research firm YouGov put the Remain vote at 52% and the Leave vote at 48%, which would mark a narrow victory for advocates of the EU after several weeks in which polling data suggested that Albion might bolt the Eurozone.

The British territory of Gibraltar was first to provide an official tally, confirming just after 3:30 PM Pacific that it had voted to remain within the EU.

An internal poll of 10,000 people conducted by the group Leave.EU already suggested a victory for Remain according to The Independent, and Nigel Farage, leader of the UK Independence Party told Britain’s Sky News earlier today that he believed Remain would win.

Both sides in the debate have fielded prominent Britons as advocates, including Jeremy Clarkson, David Beckham, Benedict Cumberbatch and J.K. Rowling arguing in favor of staying in the EU, and Michael Caine and Downton Abbey creator Julian Fellowes among those pushing to leave. The remain side has also been supported by some of British television and film’s biggest luminaries, including industry legend Lord Puttnam, Working Title’s Tim Bevan and Eric Fellner, Slumdog Millionaire producer Christian Colson, The King’s Speech producer Iain Canning and James Bond producer Barbara Broccoli.
