An UK award-winning editor/ A UK award-wining editor
I've come across an a sentence where a native speaker uses AN-article before UK (An UK award-winning editor). I wonder if it is correct variant taking into account that while speaking UK starts with a consonant.

Question

Answer

You are correct.  You need to use 'a' before 'UK'.

In fact, it's a rather odd term altogether.  Does UK refer to the award or the person?  It's presumably the latter, so it ought to be 'an award-winning UK editor'.  I wonder if it was originally that way round, and the writer simply forgot to change the article.
