What’s the most important story in Britain over the last 25 years? The financial crisis? Brexit? These events both changed our country dramatically. But neither has had such a big impact on the make-up of Britain than immigration.

In 1991, Britain’s foreign-born residents made up 6.7 per cent of the population. In 2021, one in six people (16.8 per cent) living in England and Wales were born outside the UK, according to Census data released yesterday by the Office for National Statistics.
