Following the acceptance of the Rendel and McNeice Commission recommendations, all seats in the CC were open for election, unlike the previous where elected seats made up two-thirds. Like the Legislative Assembly 1955 election, political parties were permitted to use standardised symbols. There were also several changes of alignments in the last four years. Among the incumbent City Councillors, eight from PP switched over to the new LSP. Three from LP and two independents joined the ruling LF. One each from LP and PP became independent, namely S. Jaganathan and Sim Beng Seng, who were both briefly in LF. Another two, P. R. Williams from LP who later became independent, and LF Minister J. M. Jumabhoy who was elected as independent, had resigned. LF worked with the main opposition PAP, each fielding candidates in half the number of seats and avoided contests against each other to counter the powerful LSP, which contested all seats. Former Chief Minister David Marshall, who earlier resigned from LF, established WP, which later became a renowned opposition party. UMNO and MCA were left as partners in alliance after expelling SMU for sending a candidate for the 1957 by-election. According to historical narrations, the pro-communists backed the two new entrants, PAP and WP. With that, PAP came out on top in the race, winning the most seats and all except one of its contested seats. A PAP-UMNO coalition was formed, which left out the trounced LF. WP also fared well in its first electoral foray. PAP's Ong Eng Guan was elected Mayor of the CC and became the first Mayor in Singapore.
