SYDNEY—Australian Prime Minister Anthony Albanese was returned to power in an election Saturday, the latest left-leaning leader to achieve a comeback victory as President Trump roils global markets and upends international affairs.

For the second time in a week, voters in a prominent US ally angered by President Donald Trump punished conservatives and re-elected a left-leaning incumbent.

Australians are voting in a national election this weekend, and President Trump appears to be playing an outsized role as nations continue to respond to the vision of U.S. foreign policy he's put in place in the first 100 days of his second term.
