Both newspapers have weekly book reviews, women's pages and other regular features. "The Express" and "The Mail" are different from "The Sun", "The Daily Star" and "The Daily Mirror" and are considered "middle market".*
Almost all Sunday newspapers are national ones. The quality Sunday newspapers offer large sections on literature and the art, business and sport. They come with colour supplements, free magazines or television guides. The most popular Sunday newspapers are "The Sunday Times", "The Observer", which is the oldest Sunday paper, "The Sunday Telegraph", and "The Independent on Sunday". "The News of the World", which is the best-selling Sunday "popular", has a reputation for its detailed reports of crime, sports reports and its political comment. "The Sunday Mirror" contains popular articles on celebrities, with much gossip and many photographs. "The People" offers "true life" stories and features. Both "The Sunday Express" and "Mail on Sunday" are similar to their daily equivalents in style and content.
As well as the national press, there are many regional and local newspapers. These range from dailies to Sunday papers and others that are published once a week. Regional and local papers contain features on the community as well as details of local theatre and cinema performances. Local papers are not divided into "popular" and "quality" papers. Local newspapers are usually written in a simple style. Many local papers, which usually contain nothing but advertisements, are delivered free and are called "free sheets".
