The right-leaning think tank, Policy Exchange has pointed out that in inner London a majority of primary school pupils do not have English as their first language and are questioning whether children with English as a second language will grow up to feel British, get jobs and feel included.

Neil O'Brien, the Director of Policy Exchange, says there is a huge variation over the country in the number of school children speaking English as their second language. He adds that there are in some cases smaller groups of people where integration hasn't worked out very well. The question, he says, is should more be done to actively integrate people.

Matt Cavanagh from the more left-leaning think tank, the Institute for Public Policy research, agrees that it is an issue but points out that what is encouraging is that the school results of these children are "just as good". It suggests that the school system is working pretty well, he adds.
