A big problem - google is blind

Hi all,

I have a problem that may not occur to others often. Our company has 2 travel websites <url removed> for Uk branch and <url removed>, the Uk site has PR4 and the other has PR3, they have different content, I guarantee that. The problem here is that: They often change the position of eachother on google listing. They never appear both in google, one appears, one disappears...It seems that google know 2 our websites owned by one company but why google don't list both of the 2 websites and how can google choose which site to list and hide the other.
2 week ago the .com site is on the first page of google with the keyword "vietnam holidays" now with the same position is the UK site. This happened many times.

SO do you have any ideas? can you tell me how to solve it...I want google to list both og my sites.

Thanks for your coming ideas.
