.com, .net, .org, and the country-level TLD .co.uk receive the exact match bonus.

I'm wondering if .the co.uk TLD is approved for international use like the .co extension?

I've been doing some research on the health niche and all that's available on the keyword is .info and .co.uk. I've seen some .co.uk rank on informational topics. But i questioning whether a information site based in the US word rank on the .com and that US users will click through. Though there's always the possibility that the site would get enough UK traffic to make a small investment worthwhile.
