I want to know the answer to the following question:
When did Singapore leave the Federation of Malaya?
All the background I'm provided with is that "In 1963, the 11 states of the federation together with Singapore, Sarawak and North Borneo joined to form Malaysia, but in 1965 Chinese-majority Singapore was expelled from the union following tensions between the Malay and Chinese populations.". Is that enough to answer the question?
Answer: yes
