Not sure if the guy is a billionaire, ww. Is anyone reporting that? The cladding was put on before he purchased the freehold - is it his problem, or the leaseholders who agreed to the work, or the contractor who did it, or the architect who said it was OK, or the LA who agreed to the plans?
Why is one person wholly liable?
What would happen if the govt didn't pick up the tab and there was another Grenfell? I'd rather they step in and sort it out then try and recoup the money personally. It'll cost every taxpayer 13p. If you're really bothered by it, I'll pay your share.
