People with no connection to the Post Office have told the BBC how they became engrossed watching the public inquiry into the Horizon IT scandal.

“You just sat through 1,500 shots of character performance that you were completely engrossed in,” Winquist says.

The nation was engrossed in the tale of these two charismatic yet troubled young men who seemed to have it all between wealth and looks before they violently snapped, taking their parents’ lives with shotguns.

His defence lawyer Bob Elias said he was a "lonely, socially isolated" man who had "plunged down the rabbit hole to this sort of fantasy life and became completely engrossed in it".

“That’s what we want to do — tell stories for people to be engrossed by and if they are engrossed, then job done.”
