Last week, Reform UK announced the most radical proposal on overhauling immigration by a mainstream political party in a generation. This is a British-preference immigration and welfare policy, the likes of which we have not seen since at least 1997. For example, a significant proportion of social housing tenants were born outside the UK and many of them are not British citizens. In some boroughs of London, social housing makes up over 40 per cent of all households. Thanks to Reform, the Overton window on migration and welfare has permanently moved in Britain, and a new consensus that British immigration and welfare policy should prioritise the British people and the British interest has formed.
