President Donald Trump and first lady Melania Trump have welcomed Spain’s King Felipe VI and Queen Letizia to the White House.

King Felipe described his first Oval Office meeting with the president as a “great end to a perfect visit”.

The royals were in the US to mark the 300th anniversaries of the founding of New Orleans and San Antonio, stopping in both cities with historical ties to Spain before arriving at the White House.

Mr Trump called it “really a tremendous honour” to have the royal couple in the Oval Office.

The president also praised the “outstanding” relationship between the US and Spain “over the years and, I think, especially right now.

“Excellent trade relationship, military relationship. Just about everything you can have. So we love Spain.”

Trade was expected to figure prominently in their talks.

The first lady recently resumed her schedule of public appearances following surgery last month to treat a benign kidney condition.
