Parliament has removed a video of a training session uploaded in error to its official YouTube channel.
The footage showed a livestreamed meeting with MPs' staff, teaching them how to use a new system for logging MPs' credit card expenses.
It displayed the names and faces of some of those in attendance including Hamilton West MP Gaurav Sharma, who was removed from the Labour Party caucus in August.
Parliamentary Service chief executive Rafael Gonzalez-Montero said the video had been uploaded in error.
"This video was for staff training purposes, and, like all videos we produce, did not contain any sensitive information. The video was taken down after several hours, and we have reviewed our processes to ensure this does not happen again," he said.
