conflict of interest

Being a jockey's agent and a track announcer.

From Wikipedia...

More generally, conflict of interests can be defined as any situation in which an individual or corporation (either private or governmental) is in a position to exploit a professional or official capacity in some way for their personal or corporate benefit.
Depending upon the law or rules related to a particular organization, the existence of a conflict of interest may not, in and of itself, be evidence of wrongdoing. In fact, for many professionals, it is virtually impossible to avoid having conflicts of interest from time to time. A conflict of interests can, however, become a legal matter for example when an individual tries (and/or succeeds in) influencing the outcome of a decision, for personal benefit. A director or executive of a corporation will be subject to legal liability if a conflict of interests breaches his Duty of Loyalty.
There often is confusion over these two situations. Someone accused of a conflict of interest may deny that a conflict exists because he/she did not act improperly. In fact, a conflict of interests can exist even if there are no improper acts as a result of it. (One way to understand this is to use the term "conflict of roles". A person with two roles—an individual who owns stock and is also a government official, for example—may experience situations where those two roles conflict. The conflict can be mitigated—see below—but it still exists. In and of itself, having two roles is not illegal, but the differing roles will certainly provide an incentive for improper acts in some circumstances.)
