Daily Star editor Peter Hill will act as editor-in-chief and will have overall control of the new red top, which aims to feed off its parent paper's impressive year-on-year daily circulation growth of 17% to 736,000.
The paper had originally been slated for launch in May 2002, but was postponed after staffing problems.
Industry insiders expect the arrival of a new title in the competitive weekend tabloid sector to spark a price war similar to the ongoing spat between News International's The Sun and arch rival the Daily Mirror, owned by Trinity Mirror.
News International-owner Rupert Murdoch allowed The Sun to maintain its cover price of 10p, even after the Mirror had backed down. It is thought likely he will adopt the same price-cutting strategy for the News of the World to block the rise of the Sunday Star.
Dave Harbord, a veteran of the Daily Star launch team in 1978, will become deputy editor and night editor at the Sunday Star; while former Sunday People night editor Michael Woods will be chief sub-editor.
Daily Star number three Ian Trueman is named as news editor; Ray Ansbro and Ed Barry arrive from the Sunday People to run the sports desk; as does the new art director Pippa Geeves.
