New York: Nine years ago, Donald Trump shaved off her husband’s hair after a wrestling match on live television. The President-elect nominated wrestling tycoon Linda McMahon to his Cabinet.

The perhaps most bizarre back story to any of Mr Trump’s nominations so far underscores his astonishing rise from braggadocious billionaire on the celebrity circuit to the White House taking charge on January 20 of the world’s most powerful democracy.

The incoming Republican President on Wednesday announced that he had nominated Ms McMahon to serve as head of the Small Business Administration, a Cabinet-level position. Ms McMahon met with Mr Trump in New York last week.

Mr Trump, who has promised to slash corporate tax rates and roll back regulations in an attempt to drive economic growth, called his new pick “one of the country’s top female executives.”

“She helped grow WWE from a modest 13-person operation to a publicly traded global enterprise with more than 800 employees in offices worldwide,” he said in a statement released by his transition team.

“Linda is going to be a phenomenal leader and champion for small businesses and unleash America’s entrepreneurial spirit all across the country.” Ms McMahon, 68, said she was “honoured” to have been picked.

Her wrestling-promoter husband Vince McMahon’s staged feud with his wife’s new boss culminated in a 2007 wrestling match dubbed “Battle of the Billionaires” in Detroit that was supposed to determine which tycoon had more money.
