Mr. Patrick Kenny:

A lot of competition breaches are hidden, so it is the cartel, the classic hardcore cartel - the smoky rooms, as they say. Information sharing and things like that - that are not known, that is, somebody bringing something to someone's attention that was not otherwise known. That is really the power of leniency, where somebody looks through a person's business, says it is doing something that is a problem and advises the person to bring it to the attention of the authorities.
