General People's Committee
Gaddafi abolished the post-1951 Libyan Constitution and introduced his own political philosophy, based on his "Green Book" published in the 1970s. Gaddafi's system was known as "Jamahiriya" and was notionally legally based on the legislative General People's Congress (GPC), consisting of 2,700 representatives of Basic People's Congresses, and the executive General People's Committee, headed by a General Secretary.
