You remain premier until you resign or are defeated on a vote of confidence in the legislature. You are under no obligation to surrender power before then, just because your opponents have announced they would like it. You do not want to look like you are clinging to power, and in any event the LG is unlikely to accept your request. That gives individual members a lot of power — and people with power tend to want to use it, or even abuse it. If, that is, the opposition parties are determined to vote against it, make it as uncomfortable for them as possible.
