Back to UKIP...
I see this 'observation' on places like The Guardian rather frequently although it doesn't explain much.
A large proportion of the population in places like Essex and Kent are white British people who were born and bred in London.
Due to 'white flight', the white British popultation in places like Dagenham dropped from around 80% in 2001 to under 50% in 2011. A large proportion of these people have resettled in places like Clacton in the eastern Home Counties. These people are likely to have strong views on immigration.
There are other places, like Boston where the any other white ethnic group (a good proxy for EU migration excluding Irish) increased by over 11% between 2001 and 2011. There is little infrastructure in place to cope with a large increase of population in a very short period of time, meaning local services are stretched. According to some opinion polls, UKIP is very likely to win the Boston & Skegness seat in 2015.
As someone originally from south London who has moved tens of miles north of London (for all sorts of reasons, the strongest one being p***ed off with London traffic and taking hours to drive anywhere), I can identify with that. You grow up in an area where everyone speaks the same language and broadly speaking shares a set of core values.
Then there is an influx of people with a different language and very different values who the authorities champion and make clear that in any dispute they will be given the benefit of the doubt over you.
Worse, extreme elements in those authorities try and exploit them as a trojan horse to attack your culture (as part of a cultural marxist political agenda). I remember Lambeth Councils (eventually unsucessful) attempt to ban the public Christmas Crib on Streatham Common in the 1980s because it might offend religious minorities. They backed down after a local campaign (supported by wiser members of said religious minorites).
It's not just Kent and Essex. Significant chunks of Hertfordshire, Bedfordshire, north Buckinghamshire, Milton Keynes and Northamptonshire, significant parts of Sussex as well as parts of south west England (usually older residents retiring there) and even east Surrey, aided by house prices being a fraction of London house prices in these places.
I suspect the same has occured in and around Birmingham and the northern cities. To keep it on railway terms it is one of the major causes of the increase in long distance commuting in recent years and now costing the country a fortune in rail subsidies.
Perhaps if those in charge had listed to people like
Ray Honeyford instead of hounding him out we would not be sleepwalking to division and segregation.
