A very embarrassing typo leaves Washington Post Express red-faced

We're only six days in but it's safe to say we've already seen the worst typo of 2017.

Esteemed newspaper the Washington Post has apologised after an "embarassing" mix-up on the cover of one of its free daily magazines.

The Washington Post Express led with an article about a 150,000-strong women's rights march set to take on Washington during the inaugaration of Donald Trump on January 10.

The cover showed people crowded into a shape of a gender symbol and the line "The modest start of a massive march".

It was a cover that could have been a poignant tribute to the cause - if the Express hadn't accidentally used the male gender symbol instead of a female.

"We made a mistake on our cover this morning and we're very embarrassed," the Washington Post Express said.

"We erroneously used a male symbol instead of a female symbol."

It also released an image of how the cover should have looked, promising the correct image would appear in tomorrow's paper.

This is how the cover should have looked. We apologize for the mistake. pic.twitter.com/MKKOkHPV8T
