British Airways has become locked in a sexism row with Miriam Gonzalez Durantez after she criticised the airline for referring to girls as “little princesses” in an in-flight magazine.

The high-profile lawyer, who is married to former Deputy Prime Minister Nick Clegg, said that the advertisement had made her “want to scream” on reading.

The source of her anger, an advert for a Disney branded watch from the children’s film Frozen, states that the pink-themed accessory is “the perfect watch for your little princess.”

In a public rebuke of the airline, Mrs Durantez wrote on Instagram: “When you have a 2.30 hours delay in a British Airways flight...open the inflight magazine and want to scream: Stop-calling-girls-little-princesses! It cannot be so difficult for an airline to get this right.”
