First Thing: Claudia Sheinbaum elected as Mexico’s first female president

Leftwing climate scientist and former mayor of Mexico City triumphs with a landslide, taking between 58.3% and 60.7% of the vote. Plus, Hunter Biden trial to start

Good morning,

Claudia Sheinbaum has won a landslide victory to become Mexico's first female president, inheriting the project of her mentor and outgoing leader, Andres Manuel Lopez Obrador, whose popularity among the poor helped drive her triumph.

How Sheinbaum's victory made history: Sheinbaum is the first woman to win a general election in the US, Mexico or Canada. She will also be the first person from a Jewish background to lead Mexico.

The election campaign was marred by violence: The poll has been the most violent in modern history, with more than 30 candidates killed and hundreds more dropping out as criminal groups vied to install friendly leaders.

What will prosecutors say? They intend to use Hunter's memoir Beautiful Things to make the case that he knew he was addicted to drugs when he denied it on the form that every person must fill out when buying a gun.

What does the president say? Biden has stuck by his son through all his troubles and that is unlikely to change now. But the trial could air potentially embarrassing family details.
