Do you feel the course leader is putting you under pressure?
S/he is right, it won't look good.
Perhaps you should talk to the student and find out why this situation has occurred. If your course uptake is low, and you are getting above average drop-outs and plagiarism you have a duty to find out and understand the reasons, for your own sake as well as your colleagues. Blaming the students 100% may be a simplistic view.
