In a major speech in November, the PM sought to move the debate off what he called “trade and commerce, pounds and pence” and on to “our national security”.
Three days later the world was shocked by the horror of the Paris bombings. Then came the organised sexual harassment of women in Cologne and other German cities. Now the abomination in Brussels. And, all the while, a migration crisis.
Safer in? Seriously? How are we safer as part of this collapsing project? How are we more secure giving clumsy Brussels institutions more control over our affairs?
Does it make sense for the EU to create, with Turkey, a visa-free zone that stretches from the Channel to the borders of Syria and Iran?
One by one, defence and security professionals have expressed their concerns.
Major-General Julian Thompson, who commanded our land forces in the Falklands, warns that “membership of the EU weakens our national defence in very dangerous times”.
Richard Walton, who until recently led Scotland Yard’s Counter-Terrorism unit, notes collaboration against terrorism has nothing to do with Brussels, and that “membership of the EU does not really convey any benefits”.

The former head of Interpol, Ronald Noble, says the EU’s border policy “is like hanging a sign welcoming terrorists to Europe”. Now our former intelligence chief, Sir Richard Dearlove, has written a devastating piece explaining why Britain will be safer outside the EU.
Sir Richard sees two big advantages in Brexit. First, Euro judges will no longer be able to stop us from deporting dangerous or undesirable foreigners.
Only last month, for example, we found out we couldn’t expel Abu Hamza’s daughter-in-law from the UK after a criminal conviction as it would violate her “fundamental status” as an EU citizen.
The second advantage is that we would have more control over who is allowed to enter Britain.
The Paris and Brussels atrocities tragically showed us that many potential terrorists hold EU passports.
We know, too, that Europe has lost control of its external borders, and that extremists are using the migration crisis to enter EU states.
