Gerrymandering refers to the targeted redrawing of election constituencies so as to benefit a particular party. This is especially important where the electoral system is “first past the post” in each constituency (i.e. one winner is selected in each constituency based on a majority of votes won) and where there is no other provision for proportional representation (as for example in the German system). For a simple illustration of gerrymandering, if a region consists of districts 1, 2, 3, ..., 9 with districts 1, 2, 3, 4, 5, 6 favouring party P and 7, 8, 9 favouring party Q, then grouping of districts to constituencies as , , will give two seats to party P and one seat to party Q, whereas the grouping , , will give all three seats to party P, as they will secure a majority in each constituency. Which of these statements can be deduced from the above?

Your answerChoose one option.

Gerrymandering implies that constituency boundaries can sometimes be drawn to favour one party over the other.

Gerrymandering implies that proportional representation is impossible when districts are grouped to form constituencies.
