The unfair results from the 'first past the post' voting system used in the general election. For example in the latest election, one party got 7.4% of the seats in parliament with 3.9% of the vote, whereas another got only 1.7% of the seats with 11.5% of the vote. Or there's the party that got 0% seats with 2% of the vote. We usually end up with a government that the majority didn't vote for (and that's without including the people who didn't vote). I think you have to back to the 30s for the last time a government was elected with >50% of the vote.
