Ms Oonagh McPhillips:

What was done was more or less what has been suggested by the Deputy and Deputy Clare Daly. There is a finite number of officials and their emails were trawled. It involved tens of thousands of emails in the period from December 2014, when the commission was established, to May 2016, when it published its report. The emails were trawled. The committee should be in no doubt that the trawl involved tens of thousands of emails.
