I am utterly fed up with crime writers in the UK inventing police 'partners'. systems. They are everywhere! They are NOT real! Pretty poor research!

 Note:

AI Overview

English police forces do not use an official, permanent "partner system!" like the fixed pairings often seen in American law enforcement.

(However, the concept of police working in pairs does only exist under different operational terms, and "partnership" has a completely different structural meaning in the UK.)
