is it possible to specify a region/locale for google custom search engine?

Question

I want to use the Google Custom Search API (or custom search engine directly) in the following manner--

(1) I want to get the set of results for a search term for Google UK(This should return results that are returned by a regular search on Google.co.uk- Google UK)

(2) I want to get the results for a search on Google.co.in(Google India)

Is it possible to do the above, either directly while creating a custom search engine, or through the API?
