1957 and 1959 elections

As the 1957 City Council election in December approached, a Hokkien-speaking candidate, Ong Eng Guan, became the PAP's new face to the Chinese electorate. The 32-seat city council's functions were restricted to up-keeping public amenities within city limits, but party leaders decided to contest the election as a "dry run" for the upcoming general election. Lee limited the PAP to contesting 14 seats to avoid provoking the government and formed an electoral pact with the Labour Front and United Malays National Organisation (UMNO) to jointly tackle the new Liberal Socialist Party. The PAP campaigned on a slogan to "sweep the city clean" and emerged with 13 seats, allowing it to form a minority administration with UMNO's support. Lee and the rest of the CEC unanimously endorsed Ong to become mayor.

Early in 1959, Communications and Works Minister Francis Thomas received evidence of corruption on Education Minister Chew Swee Kee. Thomas brought the evidence to Lee after the chief minister dismissed the matter. Lee tabled a motion in the assembly on 17 February, which forced Chew's resignation. As the expiry of the assembly's term approached, the PAP was initially split on whether to capture power but Lee chose to proceed. While picking the candidates, Lee deliberately chose people from different racial and education backgrounds to repair the party's image of being run by intellectuals. In the 1959 general election held on 30 May 1959, the PAP won a landslide victory with 43 of the 51 seats, though with only 53.4% of the popular vote which Lee noted.

The PAP's victory reportedly created a dilemma within the 12-member CEC as there was no formal process in place to choose a prime minister-elect. A vote was purportedly held between Lee and Ong Eng Guan and after both men received six votes, party chairman Toh Chin Chye cast the tie-breaking vote for Lee. When interviewed nearly five decades later, Toh and one other party member recalled the vote, but Lee and several others denied the account. Lee was summoned by Governor William Goode to form a new government on 1 June, to which he requested the release of arrested PAP members. On 3 June, Singapore became a self-governing state, ending 140 years of direct British rule. Lee was sworn in as Prime Minister of Singapore on 5 June at City Hall, along with the rest of his Cabinet.
