In 2022 net migration hit a record 745,000. That’s more people than live in many of Britain’s biggest cities. Last week the Office for National Statistics predicted that the population could rise by nearly 10% between 2021 and 2036. The overwhelming majority of immigrants are legal.

Economists are split on the costs and benefits of immigration. Some suggest that it could help tackle a demographic timebomb as our population ages. Britain also attracts some of the world’s most capable and highly qualified people, driving up our wealth-creating potential. National life is enriched culturally and socially. Isn’t there also a moral imperative to open our doors to people from countries troubled by war, oppression and climate change? But immigration has been high for decades without a clear electoral mandate. Some neighbourhoods have been transformed, raising concerns over social cohesion. It’s added to the pressure on housing and on creaking public services. Is it right that whole industries rely on immigrants willing to work for low pay – social care, health and hospitality?

What is a desirable level of immigration? How should the balance be struck between the demands of our economy and social cohesion? What’s the moral case for immigration?
