Also the
Access to Elected Office fund was cut at some point so anyone who needs support costs paid to campaign is shit out of luck.

Ben Fletcher stood for the Greens a few years back, he had to crowdfund interpreter support so he could do doorstepping. The video in that link is worth a watch. Ben retained his deposit and beat UKIP, reduced Justine Greening's majority from 10,500 to 1,500.
If you're lucky enough to get INTO parliament like Marsha De Cordova, then you have no legal rights to adjustments because the Equality Act doesn't apply (MPs and parliament are exempt like the judiciary, fuckers).
Marsha reports several access issues in parliament and in MPing. Often large print versions of briefings arrive after debates or later than the regular print, when it takes Marsha longer to read. IPSA retracted funding that had been agreed to fund extra human assistance for Marsha.
There's also been a refusal to consider jobsharing options for MPs where 2 people stood together as a jobshare and split the role 50:50 for people who don't have the energy for full-time (which to be fair for many MPs is a LOT of hours work if they aren't lazy). Many impairments reduce energy, and or the issue that things take longer cos of access failings.
So multiple barriers to getting access to politics, into politics, staying in politics and more.
Also, self-definition is tricky cos there are more than 6 disabled MPs, anyone with diabetes like Theresa May is legally disabled in some contexts. Several MPs have had cancer or have health conditions that would count as disabilities (several had to shield during Covid and struggled to get adjustments when others were able to return). People feel disability is a stigma so they won't recognise where they might be represented under the label.
