Ukrainian President Volodymyr Zelensky addressed the British Parliament on Tuesday via video, receiving a standing ovation. He recounted events from each of the last 13 days since Russia invaded and repeated calls for tougher sanctioning of Russia and for a no-fly zone over Ukraine.

“We will continue fighting for our land, whatever the cost,” Zelensky said. “We will fight in the forests, on the shores, in the streets.”

The refrain echoed a line from a stirring speech by British Prime Minister Winston Churchill during World War II.

“The question for us now is to be or not to be,” Zelensky said, evoking Shakespeare. “I can give you a definitive answer: It’s definitely to be.”
