What was the last colony the UK ceded marking the end of the British Empire?

The last colony that the UK ceded, marking the end of the British Empire, was Hong Kong. After 156 years of British rule, Hong Kong was returned to China on July 1, 1997, following the terms of the Sino-British Joint Declaration. The handover signaled the end of British territorial governance and the establishment of the Hong Kong Special Administrative Region under Chinese sovereignty.
