Women around the world will return to the streets this weekend, one year after millions marched to protest U.S. President Donald Trump's election, with a new goal — electing more women's rights advocates.

Trump's misogynist comments and policies rolling back birth control and equal pay efforts have propelled many women into activism for the first time, campaigners said, pointing to the success of social media campaigns against sexual harassment.

"I think that these are natural outgrowths of that outpouring of energy and they reflect some of the issues of the people who marched," Vanessa Wruble, head of March On, one group of organizers, told the Thomson Reuters Foundation.
