Donald Trump's youngest child, Barron Trump,

is to enter the political limelight with a role at July's Republican National Convention.

Delegates from across the US will formally select the party's nominee for

president at the gathering in Wisconsin - set to be Barron's father.

The 18-year-old has been named on a list of delegates-at-large to attend the event for the state of Florida.

Previously, Barron's mother Melania has kept him largely out of the public eye.

The only child from their nearly two-decade marriage,

Barron did not immediately move to Washington after his father's inauguration.

He remained with his mother at their Trump Tower home in

New York to finish his school year before they relocated in the summer of 2017.

His move to the White House, at age 11, made him the first male child to live there since John F Kennedy Jr in 1963.
