That proposal is not clear. If I understood correctly, five minutes would be allotted to witnesses; the first round of questions would be of seven minutes; and the second round would last five.
I do not know if this is something I can do now, but I would like to amend the part concerning the five-minute round, i.e., "alternating between opposition parties and government"—you will choose the appropriate wording—so that the order of the second round be the same as the first, and despite the fact that less time will be allotted to the Conservative Party, which forms a minority government in the House.
