English is not the first language for 1.8 million schoolchildren in England and new research has shown the towns and cities where most pupils speak another tongue at home. A staggering one in five pupils now speak a foreign language outside of the classroom, according to data from the Department of Education.

London has by far the most children who converse in another mother tongue, but in England as a whole 11 of the 153 local educational authorities record youngsters speaking different languages first, with Urdu, Panjabi and Polish popular primary vernaculars. The nation's capital is already one of the most diverse linguistic cities in the world,with an estimated 300 plus languages spoken across London.

Acording to the Daily Mail, the borough of Newham, in east London, has been found to have the highest percentage of kids not speaking English at home first, with a huge 66% recorded. Newham is closely followed by two more boroughs, Harrow and Brent, which have similar rates of around 63%.

Outside of the capital, Leicester is the next highest city where 55.84% of children don't speak English as a first language, Slough ranks just behind with 51.7%.

High population urban areas see by far the highest percentage rankings with more rural locations seeing much lower results. At the other end of the spectrum Cornwall has a rate of just 3.68% and Northumbria just 3.21%.

As far as interesting anomalies and contrasts go, the city of Derby has a reading of 29.89% compared to Derbyshire, which registers only 4.35%. A similar pattern emerges with Bradford in West Yorkshire which has a rate of 34.76%, whereas neighbouring North Yorkshire has just 6.71%.

Alp Mehmet, of Migration Watch UK, told the Daily Mail he believed English could become a "minority home language" across England within the next 35 to 40 years.

"English has long been the glue that holds our society together, helping new arrivals, myself included, integrate into British society," he said.

"But assimilation, when families wish to assimilate (and not all do), becomes far harder in classrooms where children are multi-ethnic, multilingual, and English is not the main language spoken at home."

In 2015 the number of schoolchildren speaking a language other than English at home was 1.1 million, but the figure has now rocketed by more than 700,000 in just 10 years.

Robert Bates, of the Centre for Migration Control, told the Daily Mail: "Language is an acute expression of culture and these figures are demonstrative of the utter transformation seen in many London boroughs in just a few decades."
