Trump will meet the Ukrainian leader, along with several European heads of state and the NATO Secretary-General, on Monday.

The last time Ukrainian President Volodymyr Zelensky was inside the Oval Office, he was berated by his US hosts, denied a planned luncheon and abruptly asked to leave the West Wing.

Amid fears of another Oval Office clash, at least six other European leaders will join Ukraine’s Volodymyr Zelensky when he meets the US president, a show of unity in the troubled effort to end the war with Russia.

The highly anticipated summit ended without a breakthrough. Afterwards, Trump said Ukraine and Russia should proceed straight to seeking a full peace deal instead of a cease-fire.

Volodymyr Zelensky has vowed to reject Vladimir Putin's "peace deal" - which involves handing large sections of Ukraine to Russia. The Ukrainian President has claimed his Russian counterpart wants the rest of occupied Donetsk - and effectively the entire Donbas region - as part of a ceasefire deal.
