The speaker of the Parliament of Singapore is the presiding officer of the Parliament of Singapore. The speaker is also second in the presidential line of succession. The incumbent speaker is Tan Chuan-Jin, who took office on 11 September 2017. Although Singapore is modelled after the Westminster system, unlike their counterpart in the United Kingdom—where the speaker must remain strictly non-partisan and renounce all affiliation with their former political parties when taking office and afterwards, the speaker of the Parliament of Singapore can choose to remain partisan.
