LONDON — Sen. Rick Scott, R-Fla., sent a letter to Britain's Prince Charles on Friday urging him to cancel a rumored visit to Cuba during an upcoming royal tour of the Caribbean.

Visiting the island long at odds with the U.S. would signal the monarch's "support for a ruthless dictatorship," Scott wrote in a letter he shared on Twitter late Friday evening.

Instead, Scott suggested the Prince of Wales and Camilla, the Duchess of Cornwall, should visit Florida to learn about the decades of "atrocities" inflicted on Cubans by the regime.

This evening I wrote a letter to Prince Charles regarding a trip he is planning to Cuba.

The visit to Cuba has not been confirmed, but NBC's U.K. partner ITV reported this week that the president of Britain's Supreme Court recently let slip the stop would be part of the tour this spring.

In a statement to NBC News on Saturday Clarence House, the office that speaks for Charles, did not comment on Scott's letter.

“All official overseas visits are undertaken at the request of the British Government,” it said.

If the couple do make the trip, it would be the first time a British royal had visited the island.

"A trip of this magnitude by the Crown provides unwarranted legitimacy to a dictatorship with a decades-long history of persecuting and imprisoning its defectors and repressing its people," Scott wrote in his letter to Charles, the heir to the U.K. throne.

Scott's approach to the Castro regime is consistent with Republican opposition to former President Barack Obama's efforts to normalize relations with the island state after a half-century of estrangement.

Ahead of the midterms, National Security Advisor John Bolton announced new sanctions against Cuba during a trip to Miami, viewed as an effort to rally conservative Latino voters in the swing state.

The sanctions are part of President Donald Trump's attempt to starve Cuba's state-run operations while channeling money to directly to Cuban people.

Relations have also been strained by a series of mysterious incidents that have damaged the health of both American and Canadian diplomats in Cuba.
