Working in the private sector at the time, Wall has been credited with playing a backroom role in the creation of the Saskatchewan Party in 1997. The party formed as a coalition of sitting Progressive Conservative and Liberal Party MLAs and members, and was intended to unify opposition to the NDP. The Progressive Conservatives have in fact not won a seat in any election since the formation of the Saskatchewan Party, and neither have the Liberals since winning 4 seats in 2003; as such, the emergence of the Saskatchewan Party has effectively created a two-party system in Saskatchewan politics.
