How did Samuel Johnson create the parliamentary debates published in The Gentleman’s Magazine?

Between 1741 and 1744, Samuel Johnson wrote a series of parliamentary reports for The Gentleman’s Magazine titled "Debates in the Senate of Magna Lilliputia." Because reporting on the House of Commons was prohibited and punishable by law, Johnson created these accounts as political fictions rather than verbatim records.1

Johnson produced these speeches based on only scant information regarding the positions held by the actual speakers, having visited the House of Commons only once himself. To add a layer of satire and distance, he utilized a Swiftian conceit, framing the debates within a fictionalized setting. Although these pieces were intended as political fictions, they were often mistaken for authentic reports by the public. Johnson eventually developed misgivings about his role in presenting these fabricated speeches as fact, which may have led him to discontinue the series.1
