It sounds as if she is eliding EU negotiators commenting on Brexit, and giving advice about the election. I'm not aware that anyone of them have done the latter, but then it won't matter to the Mail and the Express, and many Leave voters. May is posing as Britannia defeating the alien hordes, or something, and presumably it will hoover up UKIP votes and others. In a funny way, it's a rather dull election so far, so maybe some bright young Tory spads have suggested gingering it up.
