Openness and transparency is the enemy of corruption.  All British Members of Parliament are required to record their financial  interests and, if relevant, those of family members -- in a register of which is available publicly.  We are also now required to publish details of any relatives we employ, using public money.   Public companies are required to publish details of the  remuneration they pay to their directors and top management.  There are also strict rules about the funding of political parties -- it is forbidden to use public money for political purposes.  In addition, we have a relatively free press which is quick to follow up allegations of corruption and also Opposition parties who will be quick to criticise alleged corruption.
