Earlier quoted context omitted.
What are you talking about? What is misleading about this headline? It doesn't contain literally every detail, because yes you are supposed to actually read the article. As you mentioned, the important details are right there in the first couple paragraphs, not missing or buried near the end. How would you have phrased this headline?
I'm an EU citizen living in the UK, and I held my breath reading this headline. I was relieved to read alecco's comment (and the actual article). I think that's what he means: the headline sounds like she's going to kick EU citizens out. After all, the headline, as it stands, applies to me. Her actual words, very explicitly, do not. That is misleading.
However, I believe putting a control on immigration is the right thing to do.
