For anyone desperately trying to separate fact from fiction, I would recommend the Full Fact website. Here is a description of Full Fact taken from its website:
"Full Fact is the UK’s independent, non-partisan, factchecking charity. We check claims made by politicians, the media, pressure groups, and other voices in public debate, and push for corrections where necessary. We also work with government departments and academic research institutions to improve the quality and communication of technical information at source, and campaign for greater transparency in the public arena.
"We don’t support any view or political party. Our mission is to improve the quality of public debate, and to equip the public with the best information possible to make up their own minds. We provide links to all our sources so that you don’t have to take our word for anything – you can also check for yourself.
"Our commitment to transparency extends to our funding – find out more here."
This is what to say on the issue of whether there will be an EU army fullfact.org/europe/hunt-eu-army/
Its summary conclusion on the issue is, "EU member countries work together on military matters, but the EU doesn't have its own military capabilities. At least a few European politicians do support the creation of an EU army, but that would need unanimous approval. "
So in other words, the creation of an EU army would require the agreement of the UK government as well as the governments of all other EU member states. If you're interested in reading more detail on the issue, it's there on the Full Facts website.
