Keeping the url in single.php

Hi,

I’m trying to build a site but have some problems with my url / permalinks. I’ve written a loop in a template for a page, and when I click on a link to read the whole post (single.php) I want my url to be keept.

This is how it looks like right now:
https://domain.com/my-post-url

This is how I want it to look like:
https://domain.com/news/latestnews/my-post-url

Notice, news & latest news are not categories. They’re pages.
