President Volodymyr Zelenskyy is in Britain as the staunch ally of Ukraine prepares to give more military aid in an effort to change the course of the war. Zelenskyy landed by helicopter at Chequers, the British leader’s official country retreat, and was greeted by Prime Minister Rishi Sunak. It is the fourth European country Zelenskky has visited in the past few days. He made an unannounced visit to Paris on Sunday evening to meet President Emmanuel Macron, after earlier trips to Germany and Italy, meeting those countries’ leaders as well as Pope Francis. Britain said Monday it would give Ukraine hundreds more missiles and attack drones.
