I think that the hon. Gentleman has heard me respond to a similar issue before. We have repeatedly called on private building owners not to pass costs on to leaseholders, and as a result of our interventions, 216 owners have either started, completed or have commitments in place to remediate. Fifty are not co-operating, but we are maintaining pressure on them and we rule nothing out. We have established a taskforce to oversee the remediation of private sector buildings, and it is actively working to do just that.
