The Foreign Office has been ridiculed for highlighting the great design of the new Queensferry Crossing on social media - using a photo of the Forth Bridge.

Taking to their Twitter page on Tuesday evening, the Foreign Office tweeted about the brand new Queensferry Crossing that will be opening in 2017.

But in a mistake that has seemingly gone unnoticed by staff, they posted an image of the world-famous Forth Bridge - which was completed in 1890.

In the tweet, the Foreign Office said: "Opening in 2017, the 2.7km Queensferry Crossing will be the longest three tower cable-stayed bridge in the world."

They used hashtags saying #DesignisGreat and #GlobalBritain.

But the accompanying image, emblazoned with a "Design is Great Britain" logo, features a scenic view of the Forth Bridge.

The Forth Road Bridge is visible in the background while the brand new Queensferry Crossing is nowhere to be seen.

Social media users ridiculed the tweet, posting hilarious responses to the blunder.

One Twitter user, known as Citizen of Nowhere, posted a picture of New York City's Brooklyn Bridge and commented: "You've used the wrong image, I think. THIS is the Queensferry Crossing."

While another user, MajorBloodnok, countered with an image of San Francisco's Golden Gate Bridge, and tweeted: "I'm afraid you're mistaken. THIS is it."

Sandra Patterson responded with a photograph of a rickety rope bridge and commented: "Here's the one Westminster proposed".

Work began on the Queensferry Crossing over the Firth of Forth near Edinburgh in 2011.

It is due to be officially completed in May next year.
