Kamala Harris, the de facto Democratic nominee for US president, has named Tim Walz, the governor of Minnesota, as her running mate ahead of the November election.

The decision ends speculation over who Harris would pick to go up against Donald Trump, the Republican nominee and former president, and his choice for vice-president, Ohio senator JD Vance.

Walz first ran for office in 2006 in a Republican-leaning congressional district, upsetting the incumbent.

Before politics, he was a school teacher in Mankato, Minnesota, teaching geography to high school students. He also served in the Army National Guard for 24 years.
