I’m certainly no fan of LRM, but this sets a very dangerous precedent for our democracy. A sitting MP has effectively been removed from the job to which he was democratically elected because of untested allegations which he denies. Whatever he is alleged to have done, he is entitled to due process and the presumption of innocence.
Anyone who supports his suspension should be very careful what they wish for. Malicious, politically motivated allegations can be made against your allies as well as your opponents.
