The Liverpool chief executive Ian Ayre told people to “read the facts” when he was doing the PR for the club’s new ticket prices last week. I took his advice and was astonished when I saw how much disabled prices will increase next season.

The £77 tickets proposed for the new Main Stand have taken the headlines and led to the 77th minute walkout against Sunderland on Saturday. But they have overridden other significant rises, especially for disabled people.

There is a lengthy wait to acquire a disabled season ticket at Liverpool so, like many, I buy single tickets on a game-by-game basis. Over 19 Premier League games this season, comprising six category A games, 10 category B games and three category C games, the cost in the Main Stand lower is £640.50. Next season, the aggregate ticket price in the Main Stand lower for those tickets will be £1,000. That’s an increase of £359.50 – 56.13%. A disabled season ticket in the Main Stand lower in 2016/17 will cost £134.50 more than this season – £772 up from £637.50. So if you haven’t got a disabled season ticket in the Main Stand lower next season and pay on a game-by-game basis you’ll be paying a premium of £228 for exactly the same seat.

How can a price rise of such magnitude be justified for people of limited income and limited lifestyle? I find it questionable from a moral standpoint for the club to ask someone who finds it more difficult to get higher-paid work, to pay 56.13% more next season. It shows how far Liverpool have fallen from Bill Shankly’s belief that the players, manager and supporters form a holy trinity and that directors don’t come into it.

Looking at the figures for the most available seats in each stand, the aggregate ticket costs for a disabled person on the Kop next season will be £574, down from £607.50 this season and a 5.51% decrease. In the Centenary Stand it will be £854, up from £640.50 this season and a 33.33% increase, while the Anfield Road lower will increase by 5.39% from £640.50 to £675.

As an economics student at university I have to assess figures objectively but how can a football club justify a 56.13% rise in ticket prices or claim that is rational business practice, especially where disabled people are concerned? If they ostracise local people, and these rises will do, the club are not going to get many disabled supporters arriving from abroad to take their places given the complications and the difficulties that disability brings. I was talking to a supporter at the game on Saturday who travels over from Ireland and he said he wouldn’t be able to afford to go next season.

One of the reasons people are so upset is that the prices are not rational at all. As a Liverpool fan I identify with the team in so many ways but this feels like an attack because the ticket prices are so extortionate. There is distrust in the club. I feel they’ve victimised people in different parts of the ground apart from the Kop.

This season there was a six-tiered ticket price structure. That has risen to 20, which could have divided the fans into different camps over this issue and that is why the protest was so impressive. Thousands of fans were together, no matter where they sat in the stadium or how the rises will affect them.

It was incredible to walk out under the Kop on Saturday. There was very little communication at first, it was just like leaving a game after the final whistle, but then everyone started chanting: “We love you Liverpool, we do.” I’ve never really felt included before then but that is a moment I’ll take to my grave. I felt everyone was with me and everyone was behind each other.
