Lithuanian workers in United Kingdom - statistics

I noticed that there is less and less migrants arriving in Britain. In 2013-2015 there was many, many Lithuanians arriving in UK. I remember that in 2013 for example, there was big demand for Lithuanian workers in UK, as Lithuanians was in top of the list in "Top 10 foreign nationalities working in the UK" (I can't remember exact ranking, but was 1st or 2nd place, but anyway, information was from 2015) <br><br>I can also notice that few years ago if you drive through industrial estates in cities you could see many cars with Lithuanian licence plates with LT on it. Nowadays it seems like 50% of them are gone...<br><br>So, i don't really understand, why so many Lithuanians left UK? Of course, Brexit could be the main reason of this, but i never hear anything about how actual conditions were there. Is the situation the same in other countries?
