The forecast of another 10 million growth in population over the next 25 years is huge and completely unsustainable. Our schools, roads, hospitals, housing and infrastructure are already reaching breaking point. When it comes to housing alone, these numbers mean another 15,000 people per constituency will need somewhere to live on top of the massive house building required to keep up with current demand.

Pressures on local services are already high and it looks as if the situation will only deteriorate. We’ve always welcomed those from outside but the rate at which our population is growing is unlike anything we have ever experienced. Mass migration is, of course, driving much of this with 68 per cent of the increase down to immigration directly and resulting birth rates. As many as 1.7million births in the UK between now and 2039 are projected to be to foreign-born mothers. Even these figures may well underestimate the level of population increase we can expect.

The ONS figures assume that from 2020 onwards net migration per year will be running at 185,000.

We’ve always welcomed those from outside but the rate at which our population is growing is unlike anything we have ever experienced.

That seems awfully low given the current level we are running at is 330,000 per year. And that is before David Cameron, Angela Merkel and the European Union open up our borders unconditionally to 75million Turks as they intend. The minutes of the meetings between the panel who came up with these projections couldn’t be clearer: “The UK will keep outgrowing the EU with no expectation that will stop as long as the UK remains part of the EU.” In other words, unless we leave the EU, huge population growth is unavoidable.

If we want sensible numbers coming in, then we cannot have that as long as we remain inside the EU. In the run-up to the EU referendum I expect we will be quoted GDP figures as reason enough to stay in. But quality of life and people’s well-being matters more than any of that.
