Andy Burnham has called for a ban on football fans drinking alcohol in stadium stands to be scrapped, describing the law as discriminatory and outdated.
The Prime Minister said that targeting football spectators is unfair when followers of other sports are permitted to drink while watching their teams.
Established during the 1980s when fears of hooliganism were at their peak, the restriction applies to the top five tiers of English men’s football.
However, Everton fan Mr Burnham said the policy was created during "an era when football was very different".
Welcoming the Prime Minister’s comments, the Football Supporters’ Association (FSA) highlighted that successful pilots of alcohol in stands had occurred within the women’s game.
Police chiefs nevertheless warned that making adjustments without full consultation with forces would be "incredibly rash".
Mr Burnham told reporters: “I don’t think it’s fair for football fans to be singled out in that way and I made that point.
“I think that legislation dates to an era where football was very different.
“And I do believe there is a case to remove that discrimination. There are different ways it could be done, perhaps on a trial basis.
“But I’m not going to back away from what’s been a long-held view of mine. I don’t see how it can be fair that some supporters of one sport can be treated differently from others.”
The Sporting Events (Control of Alcohol) Act 1985 prohibits drinking in sight of the pitch in England and Wales in the top five men’s leagues.
FSA chairman Tom Greatrex said: “The FSA has always argued that it’s unfair to criminalise football fans for having a pint while watching the match – especially since you can sit in the same seat drinking alcohol whilst watching an Oasis gig or rugby league.
“Many clubs are in favour as well. WSL and WSL2 ran a successful pilot, meaning fans can now drink in the stands at many grounds, while the EFL has long supported a trial.
“We welcome the Prime Minister’s comments and totally agree that the legislation is outdated and deserves to be reviewed. We look forward to being part of that consultation.”
A UK Football Policing Unit spokesperson said police chiefs would welcome a meeting with Mr Burnham to “explain the challenges these proposed changes would bring to policing and the safety of staff and fans”.
The spokesperson said: ”Other sports simply don’t see the violence and criminal behaviour from their supporters that football does, albeit a minority, with alcohol often playing a significant part in violent and disorderly behaviour.
“It would be irresponsible to fuel this by allowing greater alcohol consumption during games.
“Following a number of football-related tragedies, changes in legislation were implemented after the Taylor Report for good reason and we are currently in the longest ever period without a significant football-related disaster.
“It would be incredibly rash to make fundamental changes without a full examination of the evidence and meaningful consultation with police practitioners who have the expertise in this area.”
Mr Burnham previously raised the issue shortly before entering No 10 in July, when rugby league fans were able to drink while watching matches at Everton’s Hill Dickinson Stadium.
He was at the ground with friends, including Liverpool metro mayor Steve Rotheram, who were holding pints of beer, and said: “How come these lads can do that in my seat here when we can’t do that at an Everton home game?
“Something wrong there. I think we need to look at that.”
