With a national election expected in Britain this year, in which cultural issues are likely to feature prominently, politicians from across the spectrum have commented on the design.
"Well, obviously, I prefer the original," Sunak told reporters. "My general view is that when it comes to our national flags, we shouldn't mess with them, because they're a source of pride, identity, who we are, and they're perfect as they are."
Opposition Labour Party leader Keir Starmer told The Sun newspaper that Nike should reconsider the design.
Former England goalkeeper Peter Shilton, who played for the national team at three World Cups, said there was no need to change the flag.
"I think we see a lot of changes these days with different things and I just think the colours for England, like the Three Lions, it's traditional," he told BBC radio.
Nike did not immediately respond to a request for comment on Friday.
"The trim on the cuffs takes its cues from the training gear worn by England's 1966 heroes, with a gradient of blues and reds topped with purple," a spokesperson for the U.S. sportswear giant told media this week. "The same colours also feature an interpretation of the flag of St George."
England's Football Association said it was not the first time that "different coloured St George's cross-inspired designs" have appeared on England shirts.
"We are very proud of the red and white St George’s cross – the England flag. We understand what it means to our fans, and how it unites and inspires, and it will be displayed prominently at Wembley tomorrow – as it always is – when England play Brazil," the FA said in a statement.
England play Brazil at Wembley in a friendly on Saturday, before hosting Belgium on Tuesday.
