Anna Netrebko, the superstar Russian soprano, will no longer appear at the Metropolitan Opera this season or next after failing to comply with the company’s demand that she distance herself from President Vladimir V. Putin of Russia as he wages war on Ukraine.
The end of Ms. Netrebko’s engagements, which the Met announced on Thursday, came after the opera company, citing Russia’s invasion of Ukraine,
said it would no longer hire artists who support Mr. Putin. While Ms. Netrebko has in recent days issued statements critical of the war, she has remained silent on the Russian president, whose re-election she has in the past endorsed.
