NATO chief Mark Rutte has demanded an answer today from the 'coalition of the willing' on what security guarantees will be provided for Ukraine if a ceasefire is reached with Russia.

It comes as leaders from Europe, Turkey, Australia and Canada arrive in Paris to hold talks with Ukrainian President Volodymyr Zelensky on what concrete measures they are prepared to offer Kyiv.

But the 30 countries are still divided on what they are willing to contribute, including troops on the ground, and whether such guarantees would be based on mutual defence agreements that would commit Europe to fighting with Ukraine should future conflict arise.

The summit will take place a day after scenes of powerful unity between the Russian, North Korean and Chinese leaders in Beijing, who came together for a huge military parade to mark the 80th anniversary of the end of World War Two.

Vladimir Putin and Kim Jong Un were in China at the request of Xi Jinping, who assembled over 20 non-Western countries in an anti-NATO summit designed to isolate Donald Trump. The gathering has been dubbed the 'Axis of Upheaval' by some analysts.
