Mr. Mark Hughes:

I will make a general point but I can also reply to her separately after the meeting. As I indicated, we monitor the performance of our network hourly. I will revert to the Deputy on the detail of the drive tests we perform. In addition, we listen to our customers when they call us with a query or complaint. As with all operators, we have established processes, with timeframes, for complaints. Where the issue is one of coverage, we investigate the matter and, if necessary and appropriate, send out a site engineer to ascertain if a particular issue is affecting the customer's service.
