It hasn't been discussed with the Speaker. I agree. At the same time, we know that a lot of school kids visit. When possible, if we agree in principle to look at this motion, there's always a solution. If the House of Commons and the Speaker say it's not feasible, or the security part is not feasible.... At least we can look into the principle of this.
