A fixer is someone who is assigned or contracted to solve problems for others. The term has different meanings in different contexts. In British usage (and in other Commonwealth countries) the term is neutral, referring to a person, such as a special adviser, "who...gets things done".[1] Use in American English implies that the methods used are of questionable morality and legality.[2]
In organized crime, cleaners remove incriminating physical evidence, including the disposal of bodies or witnesses. In sports, the term describes someone who makes arrangements to manipulate or pre-arrange the outcome of a sporting contest. In journalism, a fixer is a local person who expedites the work of a foreign correspondent.
