The UK prime minister said: “As the closest of allies, we stand shoulder to shoulder in defence of our shared values of freedom, democracy and enterprise.”
Elsewhere, Ukraine’s President Volodomyr Zelenskyy said he looked forward to “an era of a strong United States of America under President Trump’s decisive leadership”.
There had been questions about whether the US would continue supporting Ukraine, after former Russian president Dmitry Medvedev said a Trump win would probably be bad news for the country which was invaded by Russia in 2022.
But Zelenskyy said in a meeting Trump in September that they “discussed in detail the Ukraine-US strategic partnership, the Victory Plan, and ways to put an end to Russian aggression against Ukraine”.
He’s been joined in congratulating Trump by Israel’s Prime Minister Benjamin Netanyahu, France’s President Emmanuel Macron and Turkey’s prime minister Viktor Orban.
