US President Donald Trump's latest attempt at self-promotion has fallen flat after he misspelled the word "consequential" in a late-night tweet.

In a string of tweets last night, Mr Trump drew reference to a New York Post column by Michael Goodwin, in which the writer sings the president's praises, claiming his first year in office was "turning out to be an enormously consequential presidency".

Mr Trump however misquoted the article, citing instead his "enormously consensual presidency".

The tweet was taken down shortly after and replaced with one containing the correct spelling.

Mr Trump's gaffe however was quickly spotted and screenshotted by eagle-eyed Twitter users, the accidental – but short-lived – typo sparking mockery.

"It’s almost as if he doesn’t know the definition of consensual," one Twitter user mocked.

Some noted Mr Trump tweeted while the Golden Globe Awards were unfolding, during which many stars donned black garments in protest of workplace sexual misconduct.

New York real estate tycoon Mr Trump's presidency has been overshadowed by multiple claims of sexual harassment and assault.
