First Past the Post excludes minority parties

Minority parties are excluded if only one party is able to emerge as the winner under FPtP.

It's not Democracy if some votes count more than others, as with First Past the Post. Democracy requires proportionality which we don't have because there is only one winner in each Parliamentary seat. It would be better to take measures to encourage proportionality, otherwise it is difficult for minority parties and only mainstream parties can do well.
