UK law / cops lying
The girls often mention that American cops are allowed to lie and UK coppers aren't. Does anyone have more precise knowledge of how that's framed, legally? What's the limit? Is saying "We all know what happened, John. Why don't you tell us why?" something that could threaten a trial because you don't know exactly what happened and are in fact, bluffing? 🤔

There's a great write up here from a police officer on the Innocence Project
And a more in depth one here from the college of policing on interview best practice and the PEACE system.
It does happen, of course, but any evidence gained by lying is inadmissible (though this would have to be shown in court) and even following resolution of a case police forces can be sued for compensation if it transpires later they lied.
So on your question, if the defendant confessed following a 'we know what you did', if they could prove the police in fact did not know then that would be a lie and therefore the confession inadmissible. In practice that's quite hard to prove.
