The only surprising thing about this story is it's insidious nature. Otherwise, I would have thought it patently obvious that persons migrating from third world countries bring a third world mindset with them.
Newcomers are bound to want a say in how the country runs, if we don't like that we either stop them coming or abandon democracy.
That said, individuals responsible for these machinations need locking up for a long time or better still deporting/encouraged to repatriate.
