Mr. Plant has identified the biggest problem with majority governments; the democratic deficit "In strong majority governments, the premier and cabinet make the important decisions and the job of government MLAs is mainly just to approve them." I note that the governments in which Mr. Plant participated did nothing to address that problem. 

There are obvious answers; the easiest and in many ways the most drastic way to reduce the democratic deficit is to take the power to appoint and dismiss cabinet ministers away from the governing party leader and give it to the governing party caucus.
