A Government department has deleted a tweet including an image which showed the wrong aircraft in an advertisement for the RAF's Red Arrows.
The Department for International Trade (DIT) made the mistake while promoting the Red Arrows' upcoming tour of the US and Canada.
The silhouette in the poster resembled a Russian Sukhoi Su-30 rather than BAE's Hawk T1.
The Russian jet is almost twice as long and has a very different shape, with aircraft experts noticing the error.
A DIT spokesperson said that, following comments on social media, the post was deleted as they "wanted to be sure of its provenance".
"We think it’s best to re-post an image that more closely resembles the Red Arrows aircraft."
The spokesperson also said both the DIT and Red Arrows were "content" with the image which they argued had no affiliation to the Russian jet.
The tweet marked 48 days to go before the Red Arrows largest overseas deployment for 25 years in North America.
The nine-week tour is expected to generate £2.5 billion for Britain.
Last month, RAF Typhoons intercepted two Russian Su-30s near Estonia.
Since the incident, the DIT has published a new image.
