IPSO claims to be an independent regulator of the newspaper and magazine industry, and exists to promote and uphold the highest professional standards of journalism in the UK, and to support members of the public in seeking redress where they believe that the Editors' Code of Practice has been breached. The Editors' Code deals with issues such as accuracy, invasion of privacy, intrusion into grief or shock and harassment. IPSO is able to consider concerns about editorial content in newspapers and magazines, and about the conduct of journalists.
IPSO handles complaints, and conducts its own investigations into editorial standards and compliance. It also undertakes monitoring work, including by requiring publications to submit annual compliance reports. IPSO has the power, where necessary, to require the publication of prominent corrections and critical adjudications, and may ultimately fine publications in cases where failings are particularly serious and systemic.
