Andy Burnham has branded a ban on fans being allowed to drink alcohol in the stands during men’s football matches as “discrimination”.

The prime minister told reporters that “I don’t think it’s fair for football fans to be singled out”, as he suggested a change could be trialled.

Laws have been in place since 1985 which have prevented drinking in view of the pitch at stadiums for clubs in the top five tiers of men’s football in England. Other sports do not face such a restriction.

The Football Supporters’ Association (FSA) said the “outdated” legislation should be reviewed, but police chiefs have warned against relaxing the law and would like to meet the PM to “explain the challenges”.

The legislation was introduced in 1985 by Margaret Thatcher’s government for English and Welsh football grounds. At the time, then-Home Secretary Leon Brittan said that alcohol was a “major contributory factor in violent and disorderly behaviour” in football grounds.

Burnham is a keen football fan and a season-ticket holder at Premier League team Everton.

Shortly before he became prime minister, he criticised the restriction on football fans as he attended a rugby league game at Everton’s Hill Dickinson Stadium where it was possible for supporters to have a drink in the stands.

Speaking to reporters on his trip to the United Nations in New York, Burnham was asked if it was still his view now he is in Downing Street.

Burnham replied: “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. It could happen 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.”

A trial or pilot scheme to look at whether a change would be possible is not being ruled out by government sources.

But any wider move would require extensive consultation involving football clubs, fans and the Department for Digital, Culture, Media and Sport – none of which is currently planned.
