At the May 1991 election, The Liberal/National Government of Greiner lost ten seats, reducing its majority to 3 over Labor. However, with four independents in the crossbenches, the Government needed at least one independent to ensure a workable majority in the Legislative Assembly. After several negotiations, Greiner was able to secure the independent Member for Tamworth, Tony Windsor, agreeing to provide concessions to his electorate in exchange for Windsor's support in confidence and supply motions. Sinclair then reviewed the letters of the agreement to ascertain their legality and then commissioned Greiner as Premier. Greiner then, promising parliamentary and government reforms, signed a "Memorandum of Understanding" with the other three Independents: Clover Moore (Bligh), Peter MacDonald (Manly) and John Hatton (South Coast), to secure their support in parliament for confidence and supply.
