The parliament is redundant with first past the post which makes it similar to a democratic monarchy

There is little point having a parliament if members must be (are willing to be) loyal to their parties. But with fptp... at least the party is able to hold their leader to account to some extent. A parliament which is elected directly using pr has more ability to reject bad laws because members have no loyalty to the leader. Voting against the legislation is not a matter of rebellion. Under fptp bad laws get passed because loyalists vote through legislation without any scrutiny. If it’s better for voters not to have a choice then it is better not to have democracy. First past the post is anti-democratic.
