Singapore is holding an election on Saturday almost certain to perpetuate the unbroken rule of the People’s Action Party, in a test of public approval for its new prime minister as the city-state braces for economic turbulence from a global trade war.

Polls opened Saturday in Singapore’s general election that is seen as the first key test of support for Prime Minister Lawrence Wong, who took office last year. His People’s Action Party is widely expected to comfortably extend its 66-year dominance in the city-state.

The People’s Action Party is widely expected to continue its six-decade reign. But discontent with its policies is fueling a growing opposition.
