Immigration is now the chief concern of the people of the United Kingdom. The relentless demographic transformation of Britain, which nobody is willing to halt, is creating serious alarm among the public. That public needs to understand one thing: the legacy parties, the political class and the mainstream media engineered this change, approve of it still and are determined to enforce it, against the known wishes of the British people.

For reasons of temporary political expediency, politicians try to fob off the mug punters of the electorate with cynical promises they have no intention of fulfilling. At the last general election Dave’s pledge was “no ifs, no buts, we will get net immigration down” and he added the invitation “kick us out in five years if we don’t deliver”. His specific promise was to get net immigration down to the “tens of thousands”, generally interpreted as meaning less than 100,000 a year.

How he delivered was revealed in recent figures from the Office for National Statistics (ONS) showing that in the year to September 2014 the net immigration figure was 298,000, around 54,000 higher than the year when Dave made his pledge – another “cast-iron” promise, evidently, from this serial liar.

Sweep aside all the bovine ordure about “net” immigration. This is just a way of massaging the statistics to make them seem less threatening. The public is not interested in how many British couples left for retirement homes in Spain; in fact, their departure, so far from being a reassuring compensation, further imbalances the demographic base of indigenous Britons.

The gross (in every sense) figures are what count. The bald truth is that between September 2013 and September 2014 a total of 624,000 legal immigrants entered Britain. Such an influx, in a single year, is massive and unsustainable. And here is another key question: if EU immigration cannot be controlled, due to our loss of sovereignty, why were 292,000 non-EU immigrants (an increase of 49,000 on the previous year) allowed to enter unchallenged, by a government pledged to cut immigration?

Our culture cannot survive radical erosion on this scale. Why is this happening? Because the political class wills it, is the answer. The most revealing insight into this situation came in 2009 when Andrew Neather, a former political adviser to Tony Blair, admitted that the Labour government’s relaxation of immigration controls was a deliberate plan to “open up the UK to mass migration”, following a report from the Performance and Innovation Unit, a Downing Street think tank. Neather said the published version of the report promoted the labour market case for immigration, but unpublished versions contained additional reasons.

Neather wrote: “Earlier drafts I saw also included a driving political purpose: that mass immigration was the way that the Government was going to make the UK truly multicultural. I remember coming away from some discussions with the clear sense that the policy was intended – even if this wasn’t its main purpose – to rub the Right’s nose in diversity and render their arguments out of date.” Commentators denounced Labour’s conduct as a conspiracy. Some of us might prefer to call it treason.

To engineer a massive alteration in the demography of this country, with all the attendant problems this change wantonly created, simply to spite one’s political opponents and out of an incomprehensible hatred for the traditions and culture of one’s own country, is beyond irresponsible. A political class and system that could betray the national interest in such a manner needs to be dismantled and replaced.

Where the Labour conspirators miscalculated was in assuming that the “Right”, if that meant the Conservative Party, would resent diversity (euphemism for imposed mass immigration): on the contrary, Dave and his colleagues love mass immigration. They love it for the puerile reason they think it is “modern” and their chums in the financial world love it because it offers a pool of cheap labour, regardless of the wider cost to public services.

The ultimate expression of cynicism and contempt for the electorate is the Tories’ shameless decision to repeat the same 2010 pledge of getting “net” immigration below 100,000 in this year’s election manifesto. They must be having a laugh at the dumb voters.

The mantra of the establishment is: “Immigration is good for Britain.” In that case, why would Dave want even to pretend to reduce it? The political class believes that, while it may suffer a few casualties at the hands of UKIP, having three parties with identical immigration policies will ensure the completion of the destruction of the British identity. Only an unprecedented mass defection of the electorate to UKIP in May could reassert control of our borders. Does the British public have a sufficient instinct for survival to make that leap? Just conceivably, but don’t hold your breath.
