Former United States ambassador to Cyprus Julie Davis has resigned from her role as the country’s charge d’affaires in Ukraine after less than a year in the job amid reports of differences of opinion with US President Donald Trump.

Newspaper the Financial Times and others reported on Wednesday that Davis had become “frustrated” with her role, with Trump’s support for Ukraine openly less steadfast than that of his predecessor Joe Biden.

Those reports were denied by the US’ state department, with its spokesman Tommy Piggot saying that Davis “has been a steadfast proponent of the Trump administration’s efforts to bring about a durable peace between Russia and Ukraine”.

He added that Davis will “continue to proudly advance President Trump’s policies until she officially departs Kyiv in June … and retires from the department”.

Davis’ resignation is the latest chapter in an undulating relationship between Washington and Kyiv since Trump’s second term began last year, with Zelenskiy’s first visit to Washington after Trump’s inauguration ending with Trump and his Vice President JD Vance shouting at him on live television.

That was followed by the US briefly halting its supply of hardware and intelligence to Ukraine, though this later resumed.

Later last year, Trump met Russian President Vladimir Putin in Alaska, before inviting Zelenskiy back to Washington three days later for a second meeting.

More recently, diplomats from the US, Ukraine, and Russia held meetings in Abu Dhabi and in Geneva during the opening months of the year, with US officials having hoped that the war could be brought to an end by June.

This followed the publication of an American 28-point plan for peace which would freeze the current frontline as the de facto border between the two countries and bar Ukraine from ever joining Nato or allowing any Nato troops to entre Ukraine.

Davis had taken up her role in May last year, succeeding Bridget Brink, who had herself reportedly chosen to resign in part out of opposition to Trump’s stance on the war.

At the time, government spokesman Konstantinos Letymbiotis had praised Davis’ work on the island, saying that relations between Cyprus and the US were “perhaps at their closest, their highest level since the founding of the Republic of Cyprus”.

In her absence, Trump nominated John Breslow to the Nicosia post, though his nomination has not been voted upon by the Senate as yet.

Davis had served on the island since February 2023 and remained officially in post in Nicosia even after her appointment in Kyiv, appearing at the embassy’s July 4 celebrations last year and alongside President Nikos Christodoulides at football matches.
