Post Office computer scandal, where the Post Office's faulty Horizon computer system led to many innocent postmasters and postmistresses being falsely imprisoned for alleged fraud. The accused were finally absolved in 2021. Notable columns A series of parody columns referring to the Prime Minister of the day has been a long-term feature of Private Eye. While generally satirical, during the 1980s, Ingrams and John Wells wrote an affectionate series of fictional letters from Denis Thatcher to Bill Deedes in the Dear Bill column, mocking Thatcher as an amiable, golf-playing drunk. The column was collected in a series of books and became a stage-play ("Anyone For Denis?") in which Wells played the fictional Denis, a character now inextricably "blurred [with] the real historical figure", according to Ingrams.

The Rotten Boroughs column focusses on actual or alleged wrong-doing in local or regional governments and elections, for example corruption, nepotism, hypocrisy and incompetence. The column's name derives from the 18th-century rotten boroughs. There are also several
