Sunak accused Australian team of not following spirit of cricket.
The controversy and spice quotient upped to new levels as Jonny Bairstow was out stumped after Alex Carey hit the timber with an under-arm throw while the England batter had moved out of his crease poster ducking a Cameron Green bouncer.
The TV umpire was consulted as a result of Australians appealing and the result came out in Bairstow being given out.
While the decision has divided opinions, British Prime Minister Rishi Sunak feels it was not in keeping with the spirit of the game.
"The prime minister agrees with (England captain) Ben Stokes who said he simply wouldn't want to win a game in the manner that Australia did," the spokesman said.
In response to this, Australian Prime Minister Anthony Albanese also joined in by taking an indirect dig at the English fans and media for calling the Aussies "cheat".
"I’m proud of our men’s and women’s cricket teams, who have both won their opening two #Ashes matches against England. Same old Aussies – always winning! Australia is right behind Alyssa Healy and Pat Cummins and their teams and looks forward to welcoming them home victorious," Albanese tweeted.
