Russian politician Boris Nadezhdin, who has openly called for a halt to Moscow's invasion of Ukraine, received the 100,000 signatures by January 23 that are needed to be registered as a candidate for the March 17 presidential election. The Uzbekistan-born 60-year-old called on supporters to continue to collect signatures, especially in remote regions.
