All my political involvement is centred around disability issues - even the ones that don't affect me make me angry.
The first thing I would do would be to remove ATOS from the disability welfare assessment process. You wouldn't believe me if I started to tell you about some of the stuff going on with them. But even on the most basic level - if a person applying for disability benefits presents supporting statements from their NHS GP, their NHS consultant, their local authority social worker, their NHS physiotherapist, the butcher, the baker, and the candlestick-maker... there's no need for the taxpayer, who already paid for these public sector professionals, to pay
even more for an additional half-hour "assessment" by a private GP who has no access to the applicant's medical notes.
Having saved several million (or possibly billion - ATOS aren't terribly forthcoming with the exact figures) doing that, I would then extend the Winter Fuel Payments to include all substantially/severely disabled people on low incomes - basically the people who end up housebound by the snow and whose health is affected by extreme temperatures. I would also withdraw the WFP from anyone who went abroad for the winter, if you can afford a holiday you can afford to heat your home.
Next up, I would get rid of all those stupid schemes like Remploy and Pathways, the ones that started out with good intentions about helping disabled people into work but are now more concerned with ticking boxes to get the next bit of funding for the company cars. That really would save billions - I would divert these funds around to Access to Work, which is the DWP's own scheme that provides real, practical support (wheelchairs, sign language interpreters, screen-reading software, etc) to disabled people entering employment. Like the NHS/ATOS issue, I see no point in the public sector paying for the private sector to provide something that the public sector already provides...
There's more, but you'd all start throwing eggs at me. So to lighten the mood, I present
Mad Cap'n Tom, a parliamentary candidate I have been privileged to know for some years now, whose policies include fixing Broken Britain by issuing a free roll of duct tape to every household in the country.
