Wilson was 2-1 down and 7-4 adrift in the fourth in the men's class eight final at the Zlatorog Arena.

The victory avenged defeats to Zhao at both the London 2012 and Rio 2016 Paralympics.

"I really can’t believe it," said Wilson, who is also the Commonwealth champion.

"I have been so logical through this whole competition and today I was just trying to focus on my game, what I was doing and how I was going to win points and then all the emotion just came out at the end. 

"It's incredible. 

"I think every game was deuce apart from the second one. 

"He clinched the third at 12-10 but I had chances to win that as well. 

"After that game I just thought I'm going to have to stick in here, just keep going and keep my strategy. 

"I was down in the fourth and the fifth but fortunately I put enough pressure on him to get back in."
