Quite. The worst of the matter is that, having just checked, Employment and Support Allowance (ESA) is indeed in the list of benefits to be merged into Universal Credit (UC). The DWP, having spent six years or so trying desperately to get ESA to work, have spent at least four of those years also working on its replacement before ESA was even finished! And, at the same time, have been enduring cuts in staffing of somewhere close to 40%, at least in certain sub-departments. It is little wonder that Universal Credit is not going to be delivered on-time, ob-budget and as-planned.
It doesn't help that Iain Duncan Smith is an arrogant git, either.
