As opposed to the balanced ones? ;-)
Not sure how thousands of people can be rehoused as a matter of urgency. I agree it's a pressing problem, but with a shortage of housing stock already, it's going to be nigh on impossible. How do you even go about prioritising which people need moved first?
However, as you point out, were something else to happen, be that deliberate or accidental, then the Government would be in an even worse position.
Start with the elderly, or with children, on the top floors of the tallest buildings and work down? It obviously can't be done overnight and will be controversial but it seems to be too big a risk to wait until the cladding can be replaced.
