BRAZEN Eurocrats are set to reveal plans for an EU army the day after next month's referendum, it has been reported.
They are believed to have been working on plans foreseeing "new European military structures" since late 2014.
But the document will not be unveiled until a meeting of European leaders on June 28, sources said last night.
And Brussels chiefs are reportedly refusing to send it to governments until June 24 – the day after the in/out vote.
They fear the document could damage David Cameron's pro-EU campaign if it were to leak, according to the Times.
After a summit with EU leaders earlier this year, the Prime Minister insisted Britain "will never be part of a European army".
But the new plans, drawn up over 18 months by EU foreign policy chief Federica Mogherini, could suggest otherwise.
The policy paper says the EU "can step up its contribution to Europe's security and defence", according to insiders.
It adds: "Our external action must become more joined up across policy areas, institutions and member states.
"Greater unity of purpose is needed across the policy areas making up our external action."
Top Tory Liam Fox last night said the plans would "undermine our security to boost the EU’s aim of ever closer union".
The Brexit campaigner added: "This is our last chance to stop being dragged into a permanent EU military force."
But a Ministry of Defence spokesman said: "We will never be part of an EU army. We retain a veto on all defence matters in the EU."
