Comments come after Ukrainian leader complained his country had not been given firm timetable for joining alliance
Russia-Ukraine war – latest news updates
Britain’s defence secretary and the US national security adviser both suggested that Ukraine ought to show more gratitude for the help it had received from the west, in response to Volodymyr Zelenskiy’s complaints that his country had not been issued a firm timetable or set of conditions for joining Nato.
Their unscripted remarks – at two different events on the margins of the second day of the Nato summit in the Lithuanian capital of Vilnius – appeared to prompt a change of tack from the Ukrainian leader on Wednesday, who later said he was “grateful to all leaders of Nato countries” for their support and help.
