<h1>Prime minister to resign, triggering party leadership contest and constitutional requirement to stay until parliament approves successor</h1> A national prime minister announced plans to resign, triggering the governing party's internal leadership election and the constitutional requirement that the current leader remain in office until a parliamentary-approved successor is chosen. Markets reacted positively but noted short-term uncertainty from lame-duck leadership; analysts expect policy compromise given the party's minority position. Revised government GDP figures showing stronger growth and a finalized bilateral trade deal altering auto tariff rates were cited as market drivers. The situation raises near-term legal and political issues around leadership succession, parliamentary confirmation procedures and potential shifts in economic and trade policy.
