Which government official is responsible for crime, policing, and immigration?

The Home Secretary's role is all about maintaining order and security within the UK. Think of it as being responsible for the "home" front. This position evolved over centuries, but its modern form really took shape in the 18th century. The Home Office, the department the Home Secretary leads, deals with a wide range of issues, but crime, policing, and immigration are core responsibilities. Policing falls under their remit because the Home Office provides funding and sets the overall strategy for police forces in England and Wales. Immigration is a key part of border control and national security, so it naturally falls under the Home Secretary's watch. Crime prevention and law enforcement are also central to their role. The Chancellor of the Exchequer handles financial matters, the Foreign Secretary deals with international relations, and the Speaker presides over the House of Commons, so none of them have direct responsibility for these internal affairs.
