I have to disagree with you on point 1. 

Poor handling of covid is completely different from MP lying in Parliament framing SPF for abusing rape victim.
BTW, poor handling of covid is your own view. Not for everyone. 

But Khan admitted in Parliament she lied 3 times over months of parliamentary session.
Thus disciplinary action must be taken to ratify her grave misdeed against SPF.

You should know it is a poor comparison. 
Similah to HG Town Council mishandling the funds...
Can you ask them to quit? No.
Must let the matter settle in court.
Am I not correct? 

Point number 2 is commonsense but not related to Khan case.
Once a minister performed badly, they must be accountable. 

Point number 3.
MP post is a mandate given by voters. 

But that doesn't mean they are immune from punishment once broken the law by lying in Parliament. 
MP can be jail or fine if proven guilty in the acts of misdeed.

Lying, deliberately giving false accounts in Parliament against SPF is a grave issue. Create public hatred towards our law enforcement body.

Member of Parliament holds a even higher level in code of conduct. Because their position can create serious public division in SG.

Therefore must be serve with a higher degree of punishment to deter future misdeed from erroneous MP voted in.

Let me answer your 3 points in 1. The case is already referred to the Committee of Privileges. So let the process there handle it accordingly.. Whatever punishment need to dish out, RK have to accept it. But I doubt the Committee of Privileges can 'fired' a MP, because a MP is elected by people. Maybe only high court has the rights to do that.

If you want to drag in the HG Town Council mishandling the funds, I can also raise the similar example where Charles Cheong accused that there are missing funds in Punggol East (or West) SMC, which he never proved after election. I am also sure if 1 fine day we changed govt, we will have fun digging out mishandling everywhere, be it at Town Council, RC, Ministries etc. If not, how to explain a bus stop bench cost $1.5k..

HG Town Council mishandling the funds is magnified by media.. Every year we have lapses uncovered by AGC, but did most of them get the same limelight like HG Town Council?? Definitely no..

When I used OYK/LW as example, I am saying that we can asked them to step down from their ministerial post, but to ask them to quit as MP, or forced them to quit, it is solely with the people (GRC) who voted them in.
