From 6-2 down, Allen won eight of the next nine frames to triumph 10-7 to cap off a remarkable week of snooker.
Zhao Xintong had been looking to defend the title he won for the first time in 2021 but suffered a shock opening round UK Championship exit at the hands of Sam Craigie.
Ronnie O’Sullivan, whose seven titles give him the record number of wins at this event, was thrashed 6-0 by Ding Junhui in the quarterfinals, experiencing his first whitewash in a Triple Crown event.
Here’s how the tournament unfolded.
