Gce Model Questions Vol1 2021 Government Question 6

In a mixed‑member proportional (MMP) electoral system a parliament has \(101\) seats, of which \(60\) are constituency seats elected by first‑past‑the‑post and \(41\) are list seats used to top‑up parties to their proportional entitlement. The three parties obtain the following national vote shares and constituency wins: - Party A: \(46\%\) of the vote, \(30\) constituency seats - Party B: \(34\%\) of the vote, \(25\) constituency seats - Party C: \(20\%\) of the vote, \(5\) constituency seats Seats are allocated using the Hamilton (largest remainder) method: each party receives the integer part of its proportional share of the \(101\) seats and the remaining seat(s) are given to the party with the largest fractional remainder. List seats are then used to bring each party up to its total proportional seat count. Which party is most over‑represented (i.e., has the greatest positive difference between its percentage of seats and its percentage of the vote) after the list seats are allocated?
