David Cameron is now having to face questions on what he would do if, as looks far more likely than he would have liked at this stage, Britain votes to leave the European Union. As James predicted in his cover piece this week, Cameron will have to row back on predictions that he made about Brexit putting a bomb under the economy in order to calm nerves in the event of a Leave vote. But with the polls the way they are, the Prime Minister is already having to answer questions about whether he really believes his own warnings now, as he did on this morning’s Marr Show.

Cameron can wait to worry about turmoil in the event of Brexit. But as this morning’s interview showed, his more immediate worry about his own predictions is that people already don’t believe them and have switched off from Project Fear. The Prime Minister repeatedly said he could understand that people might find the claims and counter claims in this debate rather overwhelming.

But even if they are listening, voters might still struggle to trust the Prime Minister when, as Andrew Marr pointed out, he has made promises on immigration that he just cannot keep. MPs – particularly Labour – are reporting fury about immigration on the doorstep and this is driving a much stronger Leave vote than they had been expecting. Once again, Cameron struggled to explain how his net migration target was ever going to be met. His answers on what he had secured in the renegotiation in terms of migrant benefits were unconvincing, as he continues to ignore the impact that the living wage will have on the pull factors he is trying to reduce. And the continued prevalence of immigration as an issue means that the Prime Minister is having to talk far more about what he would practically do if Britain voted to leave than he would like at this stage.
