Creating "view desktop version" link for mobile variants

[Cloud]

I myself have found some sites just to be plain nicer on the desktop than mobile to view and read.

You must have come across a really badly designed mobile site then Rob, for a mobile site to be worse on a mobile than a desktop site on a mobile is really unfortunate.

You tend to see some rather.... interesting sites working with tech support :)

All answers so far have been about why you wouldn't want to... But to answer the original question,

This is how I would go about it:

Make a copy of your full website without a mobile version and publish this to a subfolder.

Then link the view full website button on the mobile version to this copy.

Making a copy of the site would certainly work but make sure that the search engines cannot crawl that version as duplicate content is a no-no when it comes to seo - do that by amending the robots.txt file.
