Mr. Paul Reid:

The agency cost rose from 5.8% to 6.1% of our total payroll. It is a combination of increased costs and, no doubt, staff. We have had significantly increased agency staff as part of the testing and tracing programme and the vaccination programme. Ultimately, it is a combination. It has not risen hugely as a total percentage of our pay bill. Mr. Mulvany may wish to add to that.
