Madam Speaker, it is an excellent question. It goes to show that the Leader of the Opposition knows his own limitations. He is not quite capable of maintaining opposition debate, while also ensuring the responsible behaviour of keeping national security information a secret.
I think he also sends a very damaging message to his own members' constituents by suggesting that if they have national security clearance, they are now muzzled and cannot do the job their constituents sent them here to do.
Either he does not have confidence in himself to handle the important information or he does not have faith in his own Conservative members that they can also participate in meaningful debates, while respecting the national security information of this country.
It is pretty shameful, but I am not surprised by the Leader of the Opposition. He is not able to do both things at the same time.
