The Ukrainian leader published images from an airfield showing him standing with Valeriy Zaluzhnyi, Kyiv's newly appointed ambassador to London who previously served as the head of the Ukrainian armed forces.
Zelenskiy said he planned to meet King Charles and Prime Minister Keir Starmer among others during his trip.
"We will sign an intergovernmental agreement on support for the Ukrainian defence and industrial complex, discuss future defense cooperation, and expand our defense capabilities," Zelenskiy said on X.
