The Hock Lee Bus Strike led to rioting on 10 to 12 May 1955, in which 3 people were killed and 31 injured. During the strike, large numbers of dismissed bus workers locked themselves in the Hock Lee Garages in Alexandra Road and picketed at the gates. On, 30 April 1955, the eve of May Day, sympathy strikes spread to other unions affiliated to the Middle Road Group. Dock workers stopped the transportation of freight and passengers, threatening the economic life-line of Singapore. The island-wide industrial action grew increasingly violent with the support of students from the Chinese High schools.

Business at Change Alley, which sat on prime land, saw a dwindling number of customers in the 1980s. This was attributed to a number of reasons such as the decline in sea travel, competition with modern air-conditioned shopping centres, and the withdrawal of foreign troops from Singapore. On 30 April 1989, the shops in Change Alley opened for the last time after a period of bargain sales to clear stocks. Affected stallholders were offered the option of renting sundry and cooked-food stalls at markets and food centres.

The general election of 2006 has been considered by analysts to be a landmark election in the history of Singapore, because of the heavy use of the internet and blogging that covered the election, which escaped government regulation. Just before the election, on 1 May 2006, the government issued a cash bonus, called the "progress package" to all adult citizens, worth SGD $2.6 billion. The PAP returned to power in the election winning 82 out of 84 seats, and 66% of the votes. During the election campaign period, there were large turnouts at many opposition rallies, with Malaysian newspaper The Star estimating that over ten thousand people attended one rally held on 30 April 2006.
