Dr. Tom Ryan:

It is difficult because if there is an operator or organisation where an incident occurs, there is an obligation to self-report. That is why, in the regulatory world, if we find that something has happened and an organisation has not reported it, we take it all the more seriously. On the leaks and the SF6, the regulations and appropriate powers are in place. I do not think that we have identified anything additional that we would require in that context.
