On 24 February 2022, Vladimir Putin sent up to 200,000 soldiers into Ukraine, sparking Europe's biggest movement of refugees since World War Two. The Russian president declared his goal was to "demilitarise and denazify" Ukraine and not occupy it by force. With Ukraine forming closer ties to the West and an estimated 180,000 Russian soldiers killed or wounded, we look back at the changes of the last 12 months and what may come next. On the Sky News Daily, Sally Lockwood talks to Sky's security and defence correspondent Deborah Haynes who is in Kyiv, and Ed Arnold, a research fellow for European security at the military think tank RUSI, about how Russia's aims have changed.
