Johnson told Ukraine on Tuesday that he believed it would defeat Russia and expose the "gigantic error" of the Kremlin's invasion as he invoked Britain's wartime leader Winston Churchill to underline his support for Kyiv.
Becoming the first Western leader to address Ukraine's parliament since the start of Russia's invasion on February 24, Johnson saluted the country's bravery in exploding "the myth of (Russian President Vladimi) Putin's invincibility."
Johnson spoke to the Ukrainian lawmakers via video link after standing for the country's national anthem and being introduced by the Speaker.
