Also my understanding is that man o' wars are not necessarily British. Looking at the English wikipedia article it mentions Portuguese and Dutch man o' wars. The French article, which contains a lot more information, also mentions Spanish and French man o' wars. That article simply says that the term man o' war was used by the British not that man o' wars were necessarily British.
England is now accepted. The answer still says UK purely because the places where the ships were made is now in the UK, but England is accepted now too. Thanks for your feedback!
Hmm... just looked at my pack of McVities Jaffa cakes and ingredients say Orange juice. Maybe other brands use the answer here (and McV do other flavours too like strawberry).
Also the Man o' war predates the formation of the UK so this answer could be adjusted.
