Merkel has been a regular at the annual gathering of political leaders, CEOs and celebrities, traveling to the snowy resort in the Swiss Alps seven times since becoming chancellor in 2005.

But her spokesman told Reuters she had decided not to attend for a second straight year. This year's conference runs from Jan. 17-20 under the banner "Responsive and Responsible Leadership". Trump's inauguration coincides with the last day of the conference.
