United Nations chief Antonio Guterres has cancelled his participation in this week’s Davos summit in Switzerland after coming down with a “bad cold”, a spokesman said Tuesday.

“The Secretary-General has unfortunately had to cancel his participation at the World Economic Forum’s annual meeting in Davos,” UN spokesman Rolando Gomez told reporters in Geneva, adding that Guterres had been scheduled to speak on Wednesday, but now has “a bad cold” and will be leaving Switzerland instead.

The development comes as President of the United States, Donald Trump, is expected to meet global business leaders in Davos on Wednesday, according to a Reuters report.

Quoting sources familiar with the matter, Reuters said business leaders, including CEOs in financial services, crypto, and consulting, were invited to a reception after Trump’s address to the World Economic Forum’s annual meeting, the sources told Reuters on Monday. The agenda was unclear.

One CEO simply had “a reception in honour of President Donald J Trump” scheduled in their diary, while another said their understanding was that global CEOs had been invited, not just those from the United States. One of the sources said the invitations had come from the White House.

Anthony Scaramucci, an investor who briefly served as Trump’s communications director during his first term, said he knew the meeting was happening.

Trump is expected to arrive on Wednesday in the Swiss mountain resort, where he is due to deliver a special address.

Several top U.S. officials, including Treasury Secretary Scott Bessent, are also accompanying Trump.
