A press secretary or press officer is a senior advisor who provides advice on how to deal with the news media and, using news management techniques, helps his employer to maintain a positive public image and avoid negative media coverage.
They often, but not always, act as the organization's senior spokesperson. Many governments also have press secretaries. A deputy press secretary is typically a mid-level political staffer who assists the press secretary and communications director with aspects of public outreach. They often write the press releases and media advisories for review by the press secretary and communications director. There are usually assistant press secretaries and press officers that support the press secretary. Press secretaries give also declarations to the media when a particular event happens or an issue rises inside an organization. They are expected, therefore, to have a huge knowledge about the institution or the organization they are working in and to be able to explain and answer questions about the organization's policies, views upon a particular issue and its official standpoint in problematic questions.
