Simple. They just do what every Government does when they want to make a complete U turn over an unpopular policy:
Step 1. Hail the re-introduction of the original system as a big new idea of their design. If necessary rebadge the original policy with a new name so there can be no doubt over the fact that it is "new".
Step 2. Quietly disassociate themselves from the "bad idea", and if pressed insist it was something they were saddled with from a previous Administration, and they had been trying to get rid of it as long as they've been in power.
They know they will easily get away with it because they are (in effect) bowing to public opinion anyway (albeit on their own terms), so any opposition is only to their methods, not to the policy in question.
Ask me another...
