The Regulations Review Committee did raise an issue with regard to this particular order. They were concerned around the clarity around the frequency of the testing requirement, recognising that saliva testing will need to be more frequent than the nasal pharyngeal swabs. I've considered closely the feedback from the Regulations Review Committee. I am comfortable that the order is clear and that there isn't ambiguity there, but as we continue to refine and test the orders, we will look and see whether there is simpler language that could be used in future orders just to remove any potential suggestion that that's not clear. So that particular order came into force at 11.59 p.m. on 11 August 2021.
