It can be combined with other electoral systems; in Uruguay DSV is used to elect the president and members of the Senate and Chamber of Representatives, with the presidential election also using the two-round system; if no party/presidential candidate receives a majority of the vote, a second round is held for the presidential election.

[1] The initial republican constitutions of several countries in the Commonwealth of Nations, such as Kenya,[2] Guyana[3] and Zambia,[4] provided for presidential elections by double simultaneous vote.

Occasionally, as in Tanganyika,[5][6] a variant was used whereby the candidate who won a majority of constituencies (as opposed to a plurality of votes) would be elected.

Such systems have also been used in Latin America.
