For people to believe in voting for their parliaments, their votes should reflect their wises.  In the United Kingdom this is not the case.  When a party wins by 6.8% over there closest rival party they shouldn't have 50% more seats.  This brings the electoral system into disrepute.

Conservative 36.9% 331 seats, 56.7% of seats

Labour 30.4% 232 seats, 35.7% of seats

UKIP 12.6% 1 seat, 0.15% of seats

Green 3.8% 1 seat 0.15% of seats

By having a fairer voting system the will of the people will be better represented and more people will take part in elections.
