The Daily Telegraph is publishing a 68-page tribute issue on Saturday, which will include a number of tributes, including one from the Saatchi & Saatchi co-founder Maurice Saatchi.
Saatchi was central to reforming the Conservative Party's creaking machinery and returning it to its glory days in the 1980s.
The Daily Mail, the Daily Express and The Times are among the national newspapers also expected to publish dedicated tribute issues to the former prime minister this weekend.
The Daily Telegraph’s sister issue The Sunday Telegraph is publishing a 12-page Thatcher supplement on Sunday. Rivals are also expected to dedicate significant editorial coverage to Thatcher.
