This may seem unlikely, but take note. Disability Discrimination may take place even though the employee is not him/her self disabled. If the employee is e.g. selected for redundancy in part because s/he cares for someone who is disabled then that is disability discrimination against the employee.
I have very recently advised a senior person who was made “redundant” in just such circumstances. In case you are wondering, he was not employed by one of my clients!
