Highlights of BBC’s EU Great Debate

The UK public are being asked to choose whether the UK should stay in the European Union or leave in the first vote on the UK’s links with Europe for more than 40 years.

It has been a campaign which BBC political editor Laura Kuenssberg says is too close to call, but which has changed British politics in a number of ways.

The four-month campaign comes to a close on Wednesday, with campaigners making a last-minute appeal to undecided voters, emphasising their main arguments and encouraging their supporters to turn out to vote.

Mr Cameron, who has appeared alongside ex-PM Sir John Major and former Labour leader Harriet Harman in Bristol, has told the BBC that the decision will be irreversible and there will no coming back if the UK votes to leave.

“You can’t jump out the aeroplane and then clamber back through the cockpit hatch,” he told BBC Radio 4’s Today.

Leaving the EU would be a “massive problem” for the UK, he said, doing “untold damage” to economic growth, jobs and family finances and hindering the opportunities and life chances of future generations.

The EU referendum took centre stage at Wembley Arena as the two sides traded blows before an audience of 6,000 people for the BBC’s Grand Debate.

Both campaigns had three representatives each on their respective panels, including Scottish Conservative leader Ruth Davidson for Remain and former Tory London Mayor Boris Johnson for Leave.
