Ministry of Interior and Defence

The Ministry of Interior and Defence (MID) was a ministry of the Government of Singapore. It was established in 1965, with Goh Keng Swee as the inaugural minister. The ministry was responsible for both internal and external security, controlling both the police force and the armed forces.

As the differences between the police force and the armed forces became more defined, the ministry was eventually split into the current Ministry of Defence (MINDEF) and the Ministry of Home Affairs (MHA) on 11 August 1970.
