Monday evening UK news briefing: Boris Johnson pictured at Number 10 party

Evening briefing: Today's essential headlines

Partygate pictures | Boris Johnson drank alcohol with aides at a leaving party in November 2020 while Britain was under Covid lockdown, leaked photographs show. ITV News obtained four pictures showing the Prime Minister with a glass in his hand as he stood by a table littered with bottles of wine. The second national lockdown had been imposed on the nation eight days before the gathering. Angela Rayner, deputy leader of the Labour Party, said the images mean there is "no doubt" that he lied when he said he was unaware of rule-breaking in No 10 during the pandemic. Our live blog has the latest reaction and the pictures.

The big story: Russian war criminal sentenced to life

In a conflict where technology has made the horrors of war more observable than ever, could the fate of Vadim Shishimarin be the first of many?

The Russian tank commander has been sentenced to life in prison for killing an unarmed civilian, in the first war crimes trial of the conflict in Ukraine.

The 21-year-old Russian soldier had pleaded guilty to killing Oleksandr Shelipov, 62, in the northeastern Ukrainian village of Chupakhivka on February 28 after being ordered to shoot.

A Russian diplomat has quit his post in a daring anti-Kremlin walkout today as he condemned Vladimir Putin for trying to stay in power by unleashing an "aggressive war in Ukraine".

Boris Bondarev, a councillor at the Russian permanent mission to the UN in Geneva, told the Telegraph he felt it was his moral duty to take a stand against the Russian leader's regime.

It comes as a Ukrainian intelligence chief has revealed Putin survived an assassination attempt at the start of the war in Ukraine.

Kyrylo Budanov, head of Ukrainian military intelligence, said in an interview with Ukrainska Pravda that Russian authorities thwarted a plot to kill the Russian president two months earlier.

Russian troop deaths in the first three months of the war in Ukraine are the same as Soviet losses during nine years of conflict in Afghanistan, Britain's Ministry of Defence has said.

This graph shows British and Ukrainian estimates of Russian casualties, which have not been publicly confirmed by Moscow for several weeks.

In its last update in March, the Kremlin confirmed it had lost some 1,300 troops since the invasion began a month earlier.

Brink of starvation

The extent of the human suffering caused by the war is set to reach further across the world.

Catastrophic wheat shortages risk sending millions to the brink of starvation and setting off a wave of migration as the world's poor take to the road in search of food, the International Monetary Fund has warned.

The crunch caused by Covid and the Russian invasion of Ukraine risks being compounded by misplaced protectionism as dozens of governments around the world impose restrictions on the trade of essentials including energy and food, the economic watchdog said.

David Beasley, head of the UN's World Food Programme, said Putin's blockade of Ukrainian ports "is a declaration of war on global food security," as 43 million people are "knocking on starvation's door" without exports from Europe's breadbasket.

'F-ck the war!'

It appears growing numbers of Russia's people have had enough of the pain the conflict in Ukraine is causing.

Thousands of people chanted anti-war slogans at a rock concert in Russia in a growing sign of public discontent with the Kremlin's invasion.

Concert-goers at a popular girl band show in St Petersburg were chanting "F–ck the war!" in unison in a video that was widely circulated online.

One member of the Kis Kis band has been vocal about her opposition to the war, posting criticism of the Kremlin and the invasion on her social media. Watch the chants here.

Around the world: Biden's military pledge on Taiwan

Joe Biden has said he would be willing to intervene militarily to defend Taiwan, warning that China was "flirting with danger" if it tried to seize the democratic island by force. Asked in a Tokyo press conference if – following Russia's invasion of Ukraine – he would be "willing to get involved militarily to defend Taiwan if it comes to that?" he responded: "Yes...that's a commitment we made." Mr Biden is on the second leg of his first trip to Asia, visiting both South Korea and Japan in what has been widely viewed as an attempt to bolster cooperation with regional allies in opposition to China's growing assertiveness across the Indo-Pacific.

Sport briefing: Ten Hag backs himself at Man Utd

Erik ten Hag, the new Manchester United manager, believes he can break Pep Guardiola and Jurgen Klopp’s stranglehold on English football. Read more from Ten Hag’s first press conference as Ole Gunnar Solskjaer’s long-term successor this lunchtime, less than 24 hours after Guardiola’s Manchester City clinched a fourth Premier League title in five seasons by a point from Klopp’s Liverpool. Our football writers deliver their verdicts on how all 20 Premier League clubs performed - and it makes painful reading for some.
