Thank you for that answer, Minister. There is at least a £0.5 billion backlog in building maintenance. I say 'at least' because most local health boards cannot even afford to do the assessments necessary to determine the extent of maintenance issues—maintenance issues that are impacting upon patient care. BBC Wales heard from staff at the University Hospital of Wales who stated that there were infection risks because hospital waste had to be transported in patient lifts. Minister, what is your Government doing to assess the risks to patient safety due to poor maintenance, and what will you do in future years to eliminate the repair backlog, which has been growing year on year?
