I think the metropolitan area of Leeds is a bit of a catch-all thing that includes places like Bradford and Wakefield, which bumps up the population quite significantly.

They're counting the population of the metropolitan area, which includes places like Bradford, Huddersfield, Wakefield, etc. Don't really think this should count as Leeds itself only has a population of around half a million, well below Liverpool's 1.1 million.
