BORIS Johnson has been left red-faced after seemingly being snubbed by world leaders at an emergency Nato summit.

The UK Prime Minister, who has just unveiled a raft of new sanctions against Kremlin-linked figures, was reportedly laughed at as he stood awkwardly on a stage alongside global chiefs.

Posing for the so-called “family photo” at the meeting in Brussels – called in response to the Russian invasion of Ukraine – Johnson chatted briefly with French president Emmanuel Macron and US leader Joe Biden. However, for periods both before and after the snap was taken, the PM stood alone after seemingly being snubbed by those around him.

Guardian reporter Jessica Elgot, who is at the summit, tweeted: “Amazing moment as Boris Johnson ambles up to Joe Biden after the leaders' photo at Nato, but as they begin to chat, Macron heads straight for the middle of the pair and splits them up. Whole international press room laughing.”

Footage of the awkward exchanges were shared on social media, with the Tory leader branded an “embarrassment”. Others suggest it summed up the reputation of “Global Britain”.

Ahead of the meeting in Brussels, Johnson hit the paramilitary Wagner Group – seen as Vladimir Putin’s private army – in a raft of new sanctions as he urged allies to “step up” support against the Kremlin’s invasion of Ukraine.

The Prime Minister committed to a new package, including 6000 more missiles for Ukraine and pressing to prevent the Russian president using his gold reserves.

It comes after Ukrainian President Volodymyr Zelenskyy called for worldwide demonstrations to mark a month since Russia launched its attack.

The Foreign Office said it was sanctioning 65 more entities and individuals, including Russian billionaire Eugene Shvidler and Galina Danilchenko, who was installed by Moscow as the mayor of occupied Melitopol in south-east Ukraine.

The Wagner Group plans to assassinate Zelenskyy as his forces continue to put up a far stronger resistance than many anticipated, it has been warned.

Western officials had expected to be supporting a Ukrainian insurgency at this point in the war, rather than the nation’s army, which is holding up.

Johnson said: “We’re moving, really, from a programme of supporting resistance to supporting the Ukrainian defence of their own country.”

Praising him as “one of the most extraordinary war leaders of recent times”, the PM explained Zelensky wants tighter sanctions on Putin’s regime and “very specific defensive military support” for his armed forces. “And that, we’re determined to provide,” Johnson said.

He also hit out at Moscow’s bid to host Euro 2028, saying Russia should withdraw its forces and the football tournament should be handed to Ukraine.

“The idea of Russia holding any kind of football tournament or any kind of cultural event right now is beyond satire,” he said.

“The best thing possible would be for the entire Russian armed forces to retire forthwith from Ukraine and to hand it to them, of course.”

However, those remarks came just a day after the UK and Ireland football associations submitted their joint formal interest in staging the tournament.

Six more banks were among those being sanctioned with asset freezes and travel bans, as was one of the world’s largest diamond producer Alrosa, and Polina Kovaleva, the stepdaughter of Russian foreign minister Sergei Lavrov.
