It is precisely because it is so difficult the world over to actually catch clever politicians with their hands in the till that we have laws against conflicts of interests - it is a reflection of our society's desire for good governance, not dissimilar to codes of conducts in most leading corporations in the private sector.
It may be true that there are the so-called elites who don't like you, but I can assure you that there are plenty of grass-root members of the Thai population who are also not too keen on having leaders who cheat. You got away early in your political career with an 'honest mistake' when you failed to properly disclose your assets, but how many more of these 'honest' mistakes do you think the Thai people should allow you? You are once again charged with hiding assets even now, not least the money you used to buy Manchester City. After all, you no longer even try to pretend that it was not your own money that was used to buy the football club, even though you never disclosed, as was legally required, that you ever had any money overseas.

General Saprang was probably one of the more corrupt and incompetent generals in recent Thai history. And Korn was on his payroll.
