OK HD I take your point. I was a bit brief in the first post!
Just to clear up another point from singleseater, ATC are NOT permitted to stop an aircraft making an approach due weather. They can for traffic reasons but they are not responsible for making sure minima is complied with. They just advise and report if the minima is broken. The decision to make an approach in specific weather conditions rests solely with the pilot whether it be legal or not.
