Unfortunately, there's no probably about it. Quoting Scope's research again, "Disabled people are almost three times as likely to live in material deprivation than the rest of the population (34% versus 13%)." Requiring that supporters with disabilities receive a higher rate of DLA or PIP will mean that the majority won't be eligible for a free ticket (36% receive it).
This is a forum, and people are free to share opinions. However, when the clubs' changes for supporters with disabilities aren't a Level Playing Field recommendation, and Level Playing Field won't endorse them, then you know that, objectively, the changes aren't good for supporters with disabilities.
