In 1955 at the Legislative Assembly General Election, the Labour Front Party emerged as the most number of candidates elected. Its leader David Marshall became the First Chief Minister of Singapore. He led a delegation to London in 1956 to negotiate for independence of Singapore but failed. The reason was he was too soft with the communists. In 1954, the labour unrests led by the communists were so many that it was dubbed as ‘The Year of the Strikes’. The British government wanted him to deal with the communists first before granting independence for Singapore. He resigned upon returning to Singapore. Lim Yew Hock then the Minister for Labour and Welfare took over as Second Chief Minister. He began a series of suppression against the communists. The British government then had more confidence in granting independence. From 1956 to 1968, there were a series of ‘Merdeka Talks’ for Singapore. The British finally agreed to grant self-government to Singapore in 1959 under the New Constitution. The People’s Action Party had just won the 30 May election and Lee Kuan Yew became the Prime Minister. On 1 June 1959, the General Post Office issued this set of ‘The New Constitution’ stamps. Each stamp has the Golden Lion to represent the state of Singapore with government administrative buildings in the background. Queen Elizabeth II was still the sovereign head as defence and foreign affairs were still under her control. 

On 3rd June 1960 the first National Day Stamp was issued. It was simply Singapore state flag with the words National Day. The words ‘State of’ were in cursive and SINGAPORE was in bold. June 3 1960 were printed on the left of the landscape format of the stamp. In this issue there were only two stamps – the 4 cent denomination and the 10 cent denomination. At that time 4 cent postage was used for posting an unsealed standard envelope, whereas a 10 cent postage was used for a sealed standard envelope.
