The Radical Socialist Party (RSP) was a far-left Kaskivian political party founded in 1962 by Loris Sedita as an explicit break from the moderate United Socialist Party (USP). It contested every general election from 1962 until its court-ordered dissolution during the 1994 campaign.
The RSP was never the main party of government. It usually held between 9 and 12 seats, acting as a permanent far-left critic of both the USP and the gas-boom Liberal-Conservative Party (LCP). Its parliamentary survivors regrouped as the Free League after the RSP was struck from the register; the USP and Free League were separate organisations throughout.

Dissolution (1994)
The embezzlement scandals surrounding USP leader Bettino Lanzone toxified the entire progressive left. Caught in the investigative crossfire, the RSP was formally dissolved by a Kaskivian court order due to campaign-finance irregularities during the 1994 General Election. Veteran MPs such as Aleix Monet and Gerino Melfi transferred to the newly formed Free League, which contested that same election under Melfi’s leadership. Party founder Loris Sedita retired from parliament and did not join the successor party.
