What happened the last (and only) time Putin and Zelenskyy met face to face?

Russia's Vladimir Putin will not meet with Ukraine's Volodymyr Zelenskyy for peace talks in Turkey.

Despite proposing the meeting in Istanbul, the Russian leader signed an order on Wednesday evening detailing who would be in the country's delegation and his name was not on the list. Mr Zelenskyy on Thursday travelled to the Turkish capital, Ankara, having said he would only attend the talks if Mr Putin did too.

The first was in 2019, when the two sides discussed an end to the fighting in Ukraine's eastern region of the Donbas, where Ukrainian troops had been fighting Russian-backed separatists since 2014. Here is what happened last time Mr Putin and Mr Zelenskyy came face to face.

What happened during the 2019 meeting? To try and end fighting in the Donbas region, Mr Zelenskyy and Mr Putin travelled to Paris in December 2019 for the Normandy Format Summit - an informal forum that was set up by French, German, Russian and Ukrainian diplomats after the conflict in the Donbas began. It came after Mr Zelenskyy, who had never held political office, became Ukrainian president in May of the same year.

In the election, he beat Petro Poroshenko - a billionaire confectionery magnate and former Ukrainian foreign minister - who had met and spoken directly with Mr Putin on numerous occasions, but had failed to solve the conflict with Russia. Alongside French president Emmanuel Macron and then German chancellor Angela Merkel, Mr Putin and Mr Zelenskyy sat opposite each other at a round table to discuss how they would end the conflict that had led to thousands of deaths.

The summit did lead to some agreements between the two nations. This included implementing "all necessary ceasefire support measures" before the end of 2019 and to release all prisoners of war.

Agreements were also made to disengage troops in three further areas of the Donbas region by the end of March 2020 - both Ukrainian troops and Russian-backed rebels had already pulled out of three frontline locations in the months before the meeting. Both sides also said they wished to implement the political provisions of the Minsk agreements, which were signed back in 2014 and 2015 as a first attempt to secure a ceasefire between the Ukrainian government and Russian-backed separatists.

The agreements included a roadmap for elections in the occupied regions of Luhansk and Donetsk and a plan to reintegrate the territory into the rest of Ukraine. What happened after? The 2019 meeting was seen at the time as an important step forward in ending the conflict, and some prisoner exchanges did take place, but it failed to provoke any real long-term change.

Russia and Ukraine continued to disagree on issues including the withdrawal of Russian-backed troops and elections in areas of Ukraine held by separatist rebels. The summit then took place again in Paris in January 2022, but was instead attended by representatives of Russia, Ukraine, Germany and France, not the four leaders.

In February 2022, senior diplomats met again, this time in Berlin, to try and find a way out of the conflict. Weeks later, on 24 February, Russia launched its full-scale invasion of Ukraine.

In an address to the French parliament in March 2022, Mr Zelenskyy said the invasion had "ruined" the efforts of the Normandy Format. Why does Putin's absence matter to Trump? The collapse of Thursday's face to face peace talks between Mr Putin and Mr Zelenskyy will be a "blow" for US President Donald Trump, Sky News US correspondent, Mark Stone, says.

Unlike the 2019 discussions, America has been heavily involved in trying to secure peace between the neighbouring countries. ???? Follow Trump100 on your podcast app ???? Mr Trump heavily encouraged Mr Zelenskyy to "immediately" accept the invitation to the talks in Turkey, going as far to say he was "thinking" of attending himself.

But Mr Putin's lack of attendance is a clear snub to the US leader, Stone said on the Trump 100 podcast. "It makes Trump look pretty weak, it also clearly demonstrates that Putin has absolutely no interest in a ceasefire now.

He has played Trump, as many told him he was. "All eyes will now be on Donald Trump's social media feed to see how he responds."

He said: "Beyond that campaigning bravado, Trump's stewardship over the diplomacy of the Russia-Ukraine conflict has been short of what he would have wanted. "For all the warmth towards Putin, he has been given the cold shoulder in return...

Publicly, he is talking about possibly getting on a flight, and it isn't the image of a president in control of events, it is the leader of the free world actually being led by events.".
