Do you think the british charity common purpose has sinister motives?

They are described as a charity that chooses leaders in society. It is meant to be an open organisation, but if a member of The public wants to know what our money is being spent on they put the shutters up. This 'charity' uses our tax money, people in high ranking jobs. E.g. Police inspector, headmaster, banker etc, are chosen to go on a course by common purpose. They then go back to their jobs and frequently have closed door meetings with other common purpose members in high ranking jobs to discuss pushing forward the agenda of common purpose. This obviously compromises their job integrity. The end goal agenda I believe of common purpose is the removal of a democratic government system to be replaced my a dictatorial one. The way, which will be paved by common purpose.
