Mention three former British colonies using Fitst-Past-The-Post(FPTP)

The Electoral Reform Society is an independent campaigning organisation based in the United Kingdom that advocates abolishing FPTP for all elections. It argues FPTP is "bad for voters, bad for government and bad for democracy". It is the oldest organisation concerned with electoral methods in the world.

In the US, 48 of the 50 states and the District of Columbia use FPTP to choose the electors of the Electoral College (which in turn elects the president); Maine and Nebraska use a variation where the electoral vote of each congressional district is awarded by FPTP, and the statewide winner is awarded an additional two electoral votes. In states that employ FPTP, the presidential candidate gaining the greatest number of votes wins all the state's available electors (seats), regardless of the number or share of votes won, or the difference separating the leading candidate and the first runner-up.

The multiple-round election (runoff) voting method uses the FPTP voting method in each of two rounds. The first round, held according to Block Voting rules, determines which candidates may progress to the second and final round.
