@Walter Hinteler,
OK it has been reported by and not to the embassies in Britain.
The embassies can only report what it has been told to them.
If a Swede in Germany - which has happened - was told to go back to where she came from - do you really think it was reported to the embassy or that someone from the consulte or embassy would do anything ?
Embassies can only report was has come to their ears and eyes thro media and personal telling.
Of course there has been more hate crime after Brexit as a certain type of people thought that Brexit would give them the right to behave as badly as they do.
Hate crimes have increased in EU and if the politicians do not do something really serious it will get worse and worse.
