So my question to the Minister—and there's a series of questions, and I'm hoping he'll get to all of them—is how's the roll-out for the mechanical ventilation infiltration going? Will schools have this in place by the start of term 2, before winter kicks in, and also is the Minister concerned about the wellbeing of children and their ability to focus and to learn in cold, draughty classrooms as well, because that's really important. We're knocking on the door—winter's nearly here as well.
