I feel a bit the same as Madame Folco. It's not really normal practice, but I think there could be a friendly amendment at the end, where it says “before the start of the scheduled meeting”, that would add “and subject to the minister's availability”, because as all ministers do, they try to accommodate the requests of each committee. The committee is the master of its own destiny, as we all know, but in each situation we have to do the best we can.
So I'm offering a friendly amendment to add after “meeting” the words “and subject to the minister's availability”.
