Yes, with pleasure....
To say again, my predecessors have gone back from 10 years ago, and it was really a mess. The government didn't know how many sites there were, or what the risks of those sites were. Some were since 2005 and it's particularly accelerated in recent years.
The government has prepared a national inventory. It has identified 22,000 sites. It put in a system to classify the risks to that site, so you could say if it was a class 1 or not a risk at all.
The government set out 10 steps to manage a site, whether it goes from initial assessment to full remediation to closure. It has closed 9,000 sites. So that's the progress to date and I think it's considerable.
