Russia should 'get out' of Ukraine
The former prime minister of Ukraine Arseniy Yatsenyuk has said there can be no compromise with Russia over the territorial integrity and sovereignty of Ukraine.
In March 2014, Russia annexed Ukraine's southern Crimea peninsula and a fragile ceasefire is currently holding in eastern Ukraine where Ukrainian forces and Russian-backed rebels have been fighting.
The Ukrainian businessman Viktor Pinchuk has called for a compromise where Ukraine might give up Crimea and medium-term hopes of European Union and Nato membership in exchange for peace.
But Mr Yatsenyuk told Hardtalk: "We are on the different side of the aisle, we cannot have any kind of compromise over the territorial integrity and sovereignty of my country.
"The only solution which is on the table is that Russia is to get out of Ukraine.
"It was Russia who started the war, who waged the war against an independent country, who tries to redraw the lines after the Second World War and who posed the threat to Ukraine, to you, to Nato and to everyone who stands by the values of democracy and freedom," he said.
