The decision over whether the UK remains inside the European Union could depend on whether Young people shake off their apathy and Vote in sufficient numbers on 23 June, a revealing opinion poll conducted for the Observer shows.

In a blow to David Cameron and the pro-EU camp, the online survey by Opinium puts the Leave side on 43%, four points ahead of Remain, on 39%. Some 18% of voters said they were undecided, while 1% refused to say.

While most of the “don’t knows” said, when pushed, that they were leaning towards Remain, offering hope to the pro-EU side, the survey will serve as a wake-up call to leaders of all four main Westminster parties, who are urging people to back their calls for continued membership.

Above all, it will be deeply worrying for Cameron, who will almost certainly have to resign as prime minister in the event of a vote to leave. But it also adds to pressure on Labour leader Jeremy Corbyn. Only 47% of those asked said they identified him as being in favour of remaining in the EU, while 40% said they did not know his view and 12% believed he wanted to leave. Some 78% knew that Cameron wanted to remain in.
