The new-look tabloid will feature new fonts and new sections, with the design changes aimed at broadening the newspaper's appeal.
It will also feature a new magazine - details of which are not being disclosed - that will be sponsored by Paramount Pictures, as part of the newspaper's bid to attract more upmarket brands.
The changes come a year after the Daily Mirror unveiled its redesigned paper, including new headline and body copy fonts.
Gary Jones, deputy editor of The People, said: "The relaunch is about making the paper less smutty and will feature fewer C-list celebrities."
Jones said the new-look newspaper, which will exploit Trinity Mirror's full-colour printingcapacity, has had a positive response from advertisers and agencies.
The group is also looking to lure further advertising from big brands such as Orange.
Trinity Mirror recently employed its first publishing director, Paula Scott, for The People, ahead of the relaunch.
Scott, who started in her new role last month, reports to Mark Hollinshead, managing director of Trinity Mirror's national division. Her responsibilities span editorial and commercial and she continues with her publishing role on The Wharf, the Trinity Mirror newspaper that serves Canary Wharf.
In January 2000, The People's circulation was more than 1.6 million, but it fell below the one-million mark in November 2004 and has largely been on the wane ever since.
The People's Audit Bureau of Circulations figure for February was less than 600,000 - a number dwarfed by the circulation of its rival News of the World, at more than three million, and the Sunday Mirror, at more than 1.2 million.
