Obviously his detractors will pitch it as a U turn and his supporters will pitch it as an adjustment to the criteria which is what many of his supporters objected to the time even if they agreed with the policy in principle.
Either way it will probably be enough to make it a non-issue within a few weeks and certainly before the winter.
There was some polling last week suggesting that most voters would see them in a positive light for the U-Turn.
Politicians like to screech about stuff, but ultimately, most normal people would rather get the outcome that want.
I'm curious as to why they've let it out so early, then said the details will come in the Autumn budget. My first thought was that it just leaves them open to six months of being asked for the detail constantly. The only positive reason I can think of, is that the attacks may still come, but they'll be a lot blunter. The most positive spin would be that they think any attack on the WFA now results in a narratives of "listening" and an "improving economy". Given how the last ten months have played out, I doubt the positive spin will get through, but we'll see.
