The Impact of Politics of News Manipulation in the Fourth Republic (1999 – 2006) investigated how Political manipulation of news programmes in the government – owned broadcast media can be prevented. In carrying out this study, the survey research was adopted. Questionnaires were distributed and collected. Findings showed that broadcasting and politics are inseparable, and as a result, the news programmes of the public broadcast media are always politically manipulated. Data further revealed that there are ways in which the political class manipulates news and some of which are slanting, screening, twisted diction, and timing among others. The study therefore, concludes that the political manipulation of news programmes also has implication on information dissemination in the society. On this basis, the study recommended among others, that measures should be put in place such as an in-built mechanism in safeguarding the broadcast media from future manipulation by the political class in Nigeria.
