British Prime Minister Keir Starmer and Ukrainian President Volodymyr Zelensky signed a landmark 100-year partnership agreement on Monday to deepen security ties and strengthen relations between their countries, Reuters reported.
"Today is a truly historic day, our relationship is closer than ever," Zelensky said at a joint news conference with Starmer after the signing.
For his part, the British prime minister said his government would provide a new mobile air defense system that would be "developed to meet Ukraine's needs.".
Earlier today, Starmer arrived in Ukraine on an unannounced visit to meet Ukrainian President Zelensky for the first time since he took office in July last year.
