Russia-Ukraine war at a glance: what we know on day 333 of the invasion

Former UK prime minister Boris Johnson has made a surprise visit to Ukraine, where he said that it was “the moment to double down and to give the Ukrainians all the tools they need to finish the job”. Downing Street said Rishi Sunak is “supportive” of Boris Johnson’s visit, despite warnings that it would undermine the current prime minister’s authority.

German chancellor Olaf Scholz, under pressure to allow the shipment of German-made tanks to Ukraine, said on Sunday that future decisions on weapons deliveries will be made in coordination with allies, including the United States. Scholz, when asked at a news conference about providing tanks to Ukraine, said that all weapons deliveries to Ukraine so far have taken place in close coordination with western partners.

French president Emmanuel Macron said on Sunday he does not rule out the possibility of sending Leclerc tanks to Ukraine. He was speaking at a summit with German chancellor Scholz.

The UK foreign secretary said the UK wants to see Ukraine equipped with Leopard 2 tanks. “I would like to see the Ukrainians equipped with things like the Leopard 2, as well as the artillery systems that they’ve been provided by us and by others,” he said. “I will keep having those conversations with our Nato allies and friends.”

Russia has claimed to have made advances in Ukraine’s Zaporizhzhia region. After months of stalemate in the south-eastern region, Moscow-installed officials say the front is now “mobile” while the Ukrainian army reported that 15 settlements had come under artillery fire.

Talks between government representatives from France and Germany took place in Paris, as officials mark the 60th anniversary of the Elysée Treaty and the relationship between the two nations. It comes as the two countries seek to overcome differences exposed by differing attitudes about how the continent should proceed and whether Germany will agree to send tanks to Ukraine.

German chancellor Olaf Scholz promised that Germany will “continue to support Ukraine – for as long and as comprehensively as necessary”, adding: “Together, as Europeans – in defence of our European peace project.”

Poland’s prime minister, Mateusz Morawiecki, criticised Germany’s failure to supply tanks to Ukraine. “Germany’s attitude is unacceptable. It has been almost a year since the war began. Innocent people are dying every day,” Morawiecki said.

An adviser to President Volodymyr Zelenskiy has said that caution and slow decision making over whether to send Leopard 2 tanks to Ukraine is costing lives. Mykhailo Podolyak tweeted on Saturday his frustration at “global indecision” over arms supply to Ukraine: “Today’s indecision is killing more of our people. Every day of delay is the death of Ukrainians. Think faster.”

Baltic countries have told Germany to send the tanks “now” to Ukraine after perceived heel-dragging by the government in Berlin. The Latvian foreign minister, Edgars Rinkēvičs, tweeted they are “needed to stop Russian aggression”. The same tweet was put out by his counterparts in Estonia and Lithuania.
