Proportionality Lack of representation in constituencies - MPs do not have majority support
EG. 2024 Lab Terry Jermy SW Norfolk with 26.7% of vote, only 15.7% of constit voted for him
Translates into lack of prop at a national level + winners bonus
EG. 2024 Lab won 411 (63%) seats with just 33.7% of the vote BUT 2019 worst result in modern history with 202 seats, but got 32% of vote
In contrast 2011 Scot Parl vote using AMS, SNP got 45% of vote and 53% of seats
