Re: Where does this leave Imran Khan?
Well, we cannot say that Imran is not corrupt compare to other politicians. As we can only judge a person after that person got a chance. We can look at if he is prone to corruption in places he got a chance, or not? If he was always honest in places he got chance, then we can assume that he may not do corruption if he would get chance in political post. But, can we say that Imran never did corruption? How much do you know him to say that? [Actually, there are reasons to believe that he is prone to corruption and certainly have tendency of nepotism, self-righteousness, and arrogance].
Again I do not agree with you here, that he never put himself in front of the country and that country was always first. Are you sure or do you want me to reminds some of his behaviours and actions? Think ;). Can you remember how he left Pakistan to play for Kerry Parker? Very few players were left with Pakistan and that was sad days for Pakistan cricket. Another selfish behaviour was his playing for country under captaincy of others. He always use to decline playing under captaincy of Miandad and if country want to select Imran (who always had huge source and connections behind him), Pakistan has to give him captaincy.
Even though after several tests he showed that he deserved a place in Pakistan cricket (you can say that he matured to become good player), his initial inclusion in Pakistan cricket was nothing but nepotism by some in cricket management, as well as some in civil service.
You cannot say that he is angel 
Angel do not have reasons that can make them disqualify from Pakistan parliament … chalo choro 
… as for your other statement, it is your opinion and you cannot say that with certainty that he would lead the country keeping best interest of Pakistan. Well, I don’t.
Nevertheless, from his behaviours even as player and as captain in cricket, I have lot of doubts about his capability and credibility as leader (without being bias). Few evils in him that I do not like rather hate (and same that I like most in President Musharraf, and that is the reason I like President as leader) is Imran love of nepotism, arrogance, belief on self righteousness (against any odds), regularly showing double face, blatantly lying on media, and changing political positions like lizard. He could not take criticism neither I consider him as truthful. If you watch him on TV, try to see his face (showing agony) when he is getting criticised or his argument opposed. I believe that anyone with these evils could not be good and committed leader for any country.
