Vladimir Putin “cannot remain in power” as he tries to “rebuild an empire”, Joe Biden has declared.
The US President blasted Putin as a “dictator” in a stirring speech at the Royal Castle in Warsaw, Poland.
It comes after years of claims that Putin is desperate to re-establish Russian control over former Soviet Union countries.
Biden denounced the despot after speaking to Ukrainian refugees in the Polish capital today.
When asked what he thought of Putin after the meeting, the President said: “He’s a butcher.”
In his speech outside the Royal Castle, Biden added: “In this hour, let the words of Pope John Paul burn as brightly today – never, ever give up hope, never doubt, never tire, never become discouraged. Be not afraid.

“A dictator bent on rebuilding an empire will never erase a people’s love for liberty.
“Brutality will never grind down their will to be free. Ukraine will never be a victory for Russia, for free people refused to live in a world of hopelessness and darkness.

Mr Biden said 200,000 Russians had left their country in a single month in a “remarkable brain drain” as Mr Putin, who he earlier called a “butcher”, had “strangled democracy”.
Addressing the thousand-strong audience that included refugees who have fled the war, he told Ukrainians “we stand with you – period” as he defended the nation’s president, Volodymyr Zelensky.
“Putin has the gall to say he’s denazifying Ukraine. It’s a lie, it’s just cynical – he knows that,” Mr Biden said.
“And it’s also obscene. President Zelensky was democratically elected, he’s Jewish, his father’s family was wiped out in the Nazi holocaust and Putin has the audacity – like all autocrats before him – to believe that might will make right.”
