There's no real rule here, just the conventions that Sun created with the com.sun.* packagers. The only real requirement is uniqueness and that the convention defines a folder/file structure.

What will be the decider in your case is what name you want for a 'root' folder - 'uk' or 'co'?

Right - whatever you choose, be consistent. (Not being consistent with package naming can cause real headaches, like java files split into different roots, issues with testing protected methods, etc,) – Chad Thompson Dec 17 '12 at 4:02
I meant specifically when you have to use a third-party package and it uses* while you're using*. In which case I guess it's purely cosmetic. – Andrey Dec 17 '12 at 6:53
