WHITE British people will be in a MINORITY in their own country by 2066, an expert warned last night.

David Coleman, professor of demography at Oxford University, said they will make up less than HALF the population in just over 50 years.

And soaring immigrant birthrates mean white British kids will be in a minority of youngsters in the UK even sooner. The dramatic decline will be fuelled by record-breaking levels of immigration, coupled with the departure of thousands of Brits for a better life abroad, the population analyst said.

Prof Coleman’s controversial claim will raise fresh questions about whether Britain can sustain the influx of hundreds of thousands of immigrants every year.

It comes as Home Secretary Theresa May today gets a report from the Migration Advisory Committee on what cap she should impose on migrant workers next year.

Writing in Prospect magazine, Prof Coleman warned the huge numbers of foreigners landing on our shores will “transform” the UK.

He said official projections estimate the UK’s population will rocket to 77 million by 2051 – and 85 million by 2083.

The expert went on: “On those assumptions the ‘white British’ population would decline to 45 million (59 per cent of the total) by 2051.

“Were the assumptions to hold, the ‘white British’ population of Britain would become the minority after about 2066. It’s a milestone that would be passed much earlier in younger age-groups.”

He added: “The US, by comparison, is now about 65 per cent white (non-Hispanic) and that group is projected to fall to 50 per cent by 2045.”

Even if the number of immigrants was cut so that new arrivals matched the number of Brits leaving, the “white British” population would still fall below 50 per cent by the end of the century.

Prof Coleman said this would “represent an enormous change to national identity – cultural, political, economic and religious”.
