Ukrainian President Volodymyr Zelensky hails an "unprecedented security agreement" with the UK, after UK Prime Minister Rishi Sunak announced a fresh £2.5 billion ($3.2 billion) package of support. Speaking during a visit to Kyiv by Sunak, Zelensky says "this is a reality that will come to fruition". The agreement comes amid wavering Western support for Kyiv nearly two years after the beginning of Russia's invasion. SOUNDBITE
