Languages Needed in the UK

It’s always interesting to look at what languages are trending in different parts of the world. In the United States given our demographics and geography the predominant second language sought after is Spanish for obvious reasons. In the UK, however it is a much different story. I thought this was noteworthy, the top 10 languages are……German
Dutch
French
Mandarin
Spanish
Italian
Swedish
Russian
Arabic
Japanese

If you could learn another language, what would it be and why?
