Officials in the UK said that “it’s standard practice for ministers and opposition candidates to meet.”

On Monday, Britain’s top diplomatic official met with Donald Trump, the former president of the United States in Florida as part a campaign to reaffirm its support for Ukraine.

David Cameron, United Kingdom’s foreign secretary, visits Trump just before a trip to Washington, D.C., in which the former British Prime Minister is due to meet Secretary of State Antony Blinken, and congressional leaders, over the next couple of days. Cameron will discuss with his allies a variety of issues, including “bringing peace to the Middle East”.

A spokesperson for the U.K. Government said that “it is a standard practice for ministers in their international engagement to meet with opposing candidates.” Cameron met Sen. Mitt Romney when Romney ran for president, and Cameron was Prime Minister.

Cameron’s visit comes as the White House is pushing Congress to approve a new package of aid for Ukraine to help it in its war with Russia. The 60 billion dollar package has been stuck in the House, even though it was approved by the Senate nearly two months earlier.

Cameron and his French counterpart wrote a joint opinion piece in which Cameron warned that “we will all lose” if Russian President Vladimir Putin wins the Ukraine.

Cameron stated in a press release distributed by the British embassy that “success or failure for Ukraine, and for Putin is vital for American and European Security.” This will demonstrate that borders are important, that aggression does not pay off and that countries such as Ukraine have the right to decide their own future. “The alternative would encourage Putin to continue his attempts to redraw European borders through force and would be clearly heard in Beijing, Tehran, and North Korea.”

Trump has said repeatedly that if elected president he could end the conflict. However, the Washington Post reported on Sunday that part of Trump’s plan called for Ukraine to give up some of its land to Russia. In a statement to the New York Post, the Trump campaign claimed that the Post’s story was “fake” news.

The Sun was the first to report the meeting between Cameron and the former Republican President. A Trump spokesperson has not responded to a request for comments.

Cameron has spoken out against Trump before. Cameron criticised Trump just two months ago for a comment he made during a campaign event suggesting that he would allow Russia to invade NATO allies who were “delinquents” in their spending commitments. Cameron wrote in a memoir that Trump’s ban on people from Muslim-majority countries entering the U.S. was “divisive and stupid”
