Also it may be worth you reading section 172, chapter 10 of the UK companies act 2006. The directors of a company have a responsibility to act in the best interests of all share holders. Including minority shareholders.

The company going private doesn't change the governance of this law. So if they haven't reached the 90% mark an audit of the company can be requested by as little as 10% of the vote and a general meeting requested by as little as 5% of the vote.

I don't think they will get to 75% though so even if they change directors the new directors will still be bound by the Companies Act 2006
