An estimated 450 Russian soldiers have died in the conflict in Ukraine so far and Vladimir Putin failed in his military objectives on the first day of fighting, the UK defence secretary has said.

Wallace also rebuffed pleas from Ukrainian and some Conservative politicians for the UK to implement a no-fly zone over Ukraine, arguing that introducing one would amount to declaring war on Russia.
