Unless the interpretation is incorrect, I gather from Mr. Davies that he was referring to the witnesses having seven minutes to speak. In addition, to ensure that the parties have the time to ask their questions, he wants us to remove “at the discretion of the Chair” so that we have six minutes.
I understood that the witnesses' presentation time would be increased from five to seven minutes. I think that, when we conduct a study, we must give the witnesses the necessary time to share what they have to say. I think that, when people are asked to come, it's important to give them a minimum amount of time to speak.
I think that it would be more appropriate to spend seven minutes rather than five minutes hearing from the witnesses, and to keep the six minutes of speaking time in the first round.
