On whether it should be mandatory or not to wear the headsets, absolutely it should be. It is appended to our brief. We make recommendations to that effect. The headset must be mandatory, as well as a hard-wired Internet connection.
You are quite right that headsets are not all equal, and recommendations can be made to that effect as well. We'd be pleased to provide you with what we feel is best. The House administration is, I believe, handing out headsets to all MPs and we urge you to wear them.
