ESA is the successor to Incapacity Benefit and claimants are required to go through a series of tests to judge their fitness for work.
The department has released the results from 1.3 million tests over a period of more than two years which showed:
7% were incapable of any work
17% were able to do some sort of work given the correct support
39% were deemed to be fit for work and were moved onto jobseeker's allowance
36% dropped out of the application process
1% of applications were still in progress

I knew that some people were abusing the system but this is shocking and shows that it is a worthwhile exercise.
The problem is who are going to employ these people when there are over 2 million out of work?
