Suspension of the British Guiana constitution, 1953
After Cheddi Jagan's People's Progressive Party won 18 of 24 seats in the 1953 election, Britain suspended the constitution and removed his government in October 1953, sending in troops amid concerns over his party's reform program and communist sympathies.
Significance here: A formative episode of British intervention that shaped subsequent Guianese politics through the 1960s.
