UK pledges new military assistance for Ukraine after PM's surprise visit to Kyiv
Johnson and Austria's Chancellor Karl Nehammer made separate visits to Zelensky on Saturday, the latest in a string of leaders to travel to the country during the ongoing Russian invasion.
A photograph tweeted by Ukraine's Embassy to the UK showed Johnson seated opposite Zelensky at a table in a pink and green stuccoed room. The post was captioned with the word "Surprise" and a winking face emoji.
The Press Service of the National Security and Defense Council of Ukraine said on its official Twitter account that the two leaders had held talks in Kyiv, posting several photographs of the pair's previously unannounced meeting.
Johnson posted on Twitter that his visit to Kyiv was "a show of our unwavering support for the people of Ukraine" and announced a new package of financial and military aid.
"Ukraine has defied the odds and pushed back Russian forces from the gates of Kyiv, achieving the greatest feat of arms of the 21st century," the UK PM said in a statement.

"We will influence Russia's ability to use its energy resources," he added. "The war determines the vision of Ukraine's future, so our partners and I will supply Ukraine with equipment, technology, intelligence so that Ukraine never faces the horrors of invasion and blackmail."
Following the meeting, Downing Street said the UK government would provide armored vehicles and anti-ship missile systems, "in addition to the £100 million worth of high-grade military equipment" announced on Friday.
Zelensky and Nehammer's meeting was separate to the one with Johnson and happened earlier on Saturday, according to Zelensky's official Telegram channel.
