In politics, the Party is more important than the individual. Absolutely. Leaders come and go. The Party remains. I've worked within two. That's how it works. Any leader who believes they are worth more than their Party is either leading a cult of personality (thus not a party) or has failed to understand that their ego is drastically over-inflated.

I cannot over-emphasize that politics is a different animal than any career. Politicians know this. They get the positions they do based on political considerations and lose it often based on the same. Lies do in politicians all the time. So do truths. So do uncertainties. People vote for and against politicians for reasons varying from the good to the very bad. It's not fair, but politics aren't fair. Should politicians lose positions based upon allegations? Absolutely. They can also muster sufficient political power to keep their positions despite allegations -> look at Trump.

Can bad results come from this sort of thing? Absolutely. In politics, that happens often.

I often say with Brown that I have made the decision to suffer his resignation if it was wrong to do because I am not willing to wait to see if they are found true when he's Premier.

I have other posts to write on this, including one as to why "innocent until proven guilty" isn't likely reliable here and is not the accepted standard in politics anyway.
