Poster Laughing Spam Filter posted a link to this article in another thread, but I think it deserves more prominence. England has laid out a series of "not-before" dates for loosening of pandemic-related restrictions. At the end of the article the underlying assumptions are given. The other components of the UK may end up with different paths forward.
The reference to "international travel" is open to interpretation. I assume it refers to outbound travel by residents of England.
