Answer Details
The manipulation of boundaries of constituencies in order to win more seats is called "gerrymandering". This means that the borders of electoral districts are deliberately redrawn to favor a particular political party or group. This can be done by creating boundaries that group together voters who are likely to support a certain party, or by splitting up areas that traditionally vote against a particular party. The goal of gerrymandering is to give one political party an unfair advantage in elections, by ensuring that they win more seats than they would if the boundaries were drawn fairly. Gerrymandering is considered to be undemocratic and can undermine the integrity of elections.
