A student group at the University of California, Berkeley, that was organizing a series of speeches by right-wing figures canceled the planned four-day event on Saturday but one of its featured speakers, the conservative provocateur Milo Yiannopoulos, said he would show up anyway.

The student group, the Berkeley Patriot, had been planning the event, called Free Speech Week. It was to feature Mr. Yiannopoulos and other right-wing commentators, including Mike Cernovich, Pamela Geller and Lucian B. Wintrich.

After learning of the cancellation, Mr. Yiannopoulos said he would be at the university’s Sproul Plaza at noon on Sunday along with Mr. Cernovich, Ms. Geller and others.

“I was somewhat blindsided by the announcement from the Berkeley Patriot this morning,” he said at a news conference on Saturday. “We are going to be hosting an event, come hell or high water,” he added.
