This was the last time Prime Minister Lee Kuan Yew led the PAP in an election.

[2] In November 1990, two years after the election, the Nominated MP scheme was implemented to introduce non-partisan voices into the legislature.

Although the law allowed up to six NMPs, two were appointed at the start and served for a year before the Parliament term ended.

With the Singapore Democratic Party leader's Chiam See Tong sole victory in the seat of Potong Pasir, two Non-Constituency MP seats were offered to former solicitor-general and Law Society president, Francis Seow and veteran politician Dr Lee Siew Choh, both of which were standing under the WP ticket in Eunos Group Representation Constituency; their campaign was notable for criticizing PAP for alleged dubious financial circumstances; in response Minister of State Tay Eng Soon went to lead their PAP team for Eunos.

Despite losing by a narrow margin of 49.1%-50.9%, WP were eligible for the NCMP; however, Seow fled the country on 17 December to avoid arrest and was disqualified from the post while Lee took up the offer and became Singapore's first NCMP, marking Lee's return to Parliament after 25 years since his last stint as a PAP and BS legislator.
