In June 1965, less than two months away from Singapore's separation with Malaysia, UPP chief and only Assembly Member Ong Eng Guan resigned his seat and retired from politics. This very last LA election inadvertently became a straight fight between the two main parties of PAP and BS and both fielded former AMs as candidates. By then, PAP was a national party with presence in Malaysia despite winning only one out of the 11 seats it contested in the 1964 Federal election. Due to the timing, PAP victor Lee Khoon Choy was never sworn in at the LA but at the first session of the new Parliament, convened four months after independence. In the aftermath, PAP Malaysia was converted to the Democratic Action Party by its leadership under sole legislator C. V. Devan Nair, replacing the "lightning" symbol with a "rocket". A few years later, Nair quit Malaysian politics and returned to Singapore, while DAP remains a key political party in the Peninsular and Penang until today.
