At that point, yelling is heard on the video feed from the House of Commons and Regan repeats, "which would he prefer?"

Regan then asks the Sergeant-at-Arms to remove B.C. MP Richards.

The Sergeant-at-Arms is responsible for safeguarding the authority of the House of Commons and for the safety and security of the Parliamentary precinct.

According to MPs within the chamber at the time of the incident, Richards was followed into the House lobby by the Seargeant-at-Arms.
