The government collapsed when Ben-Gurion resigned on 31 January 1961, over a motion of no-confidence brought by Herut and the General Zionists in the wake of the Lavon Affair. When Ben-Gurion was unable to form a new government new elections were called. Serving one year and nine months, the fourth Knesset was the shortest Knesset term until the five-month twenty-first Knesset in 2019.
