I feel like I've answered this question many times before, but once more unto the breach...
Firstly, the French receive around 5x the asylum claims we in the UK receive, and it's already been explained how Germany has done far more than its share, so leave off on the anti-Euro tub thumping.
Secondly, as with any migration, refugees have a desired location for any number of reasons, whether that's the language, the presence of family members, or wider diaspora. There may be better job prospects, or in Tommy Robinson's case, the weather. For those same reasons, it's very common for refugees to move within a country from the place they've been assigned. It's hard to see why this is surprising tbh.
It makes economic sense for countries to find ways for refugees to be fruitful members of their host communities, but many refugees move on from the places they are originally settled in by officials. New research explores why that is.
