Mr Bates vs The Post Office, the ITV drama which renewed attention on the Horizon IT scandal, has added another National Television Award to its list of achievements.
The four-part miniseries picked up the new drama prize at the annual awards ceremony at the O2 in London on Wednesday evening.
It saw off tough competition from Netflix hit Baby Reindeer, romantic drama One Day, and thrillers Fool Me Once and Red Eye.
Toby Jones also secured the best drama performance gong for his role as former sub-postmaster Sir Alan Bates, one of more than 550 claimants who have brought legal action against the Post Office.
Collecting the award, actress Monica Dolan, who played Jo Hamilton in the series, said: "We were so grateful and proud (of) the audience response to this drama anyway, so to win this award is absolutely incredible."
Dolan thanked the team behind the ITV drama, the actors and the subpostmasters for "trusting us to tell their story", adding that it has been "the privilege of our lives".
The star-studded ceremony also saw Anthony McPartlin and Declan Donnelly cement their status as kings of TV presenting as they won the gong for a historic 23rd year in a row.
Collecting the gong, Donnelly said: "Thank you - it's really hard to put into words just how this feels and what it means to us that you take the time to vote for us."
McPartlin described the gong as a "joy" and joked that one day they will not collect it, but tonight was not the night.
They also thanked their teams and families before reflecting on how their lives have changed over the years, especially since becoming fathers.
The duo kicked off their successful night by picking up the Bruce Forsyth entertainment award for the reality series I'm A Celebrity... Get Me Out of Here!, which they host.
Elsewhere, Kate Garraway completed a hat-trick in the best authored documentary category and dedicated the award to her late husband Derek Draper.
She won the gong for Kate Garraway: Derek's Story, which followed the final year of Draper's life before he died in January aged 56 after a lengthy battle with the long-term effects of Covid.
