Mr. Michael O'Leary:

Vulnerable people had to register primarily on medical grounds or about concerns they may have had. It was voluntary registration and a matter of whether people deemed themselves vulnerable. We did not question it. Some of those customers may be highly vulnerable, such as those on dialysis, so they really need to be kept up to date. We do not pry into what the circumstances of others are. There is an immediate call-out to those vulnerable customers in the event of an incident with water.
