The Sunday People looks set to lose both its editor and and deputy editor as its editorial team is merged with the Sunday Mirror.
Parent company Trinity Mirror announced the merger plan in July and warned that up to eight editorial jobs could go.
It is understood that editor James Scott and deputy Nick Buckley are both to leave Trinity Mirror.
It is expected that Daily Mirror Saturday and Sunday editor Alison Phillips will also take on responsibility for the Sunday People.
Both Scott and Buckley remain on police bail after being arrested in March 2013 on suspicion of conspiracy to intercept voicemails.
In July the Sunday People had exclusive photos of an England football fan who had part of his ear bitten off in Brazil.
In June 2013 the paper had a major exclusive when it published photos of TV chef Nigella Lawson being attacked by her then husband Charles Saatchi outside a restaurant.
In July, sales of the Sunday People fell 9.5 per cent year on year to an average of 379,500 a week. This was marginally better than the 10.8 per cent year on year drop experienced by the Sunday Mirror (to 932,978) and significantly better than the 13.1 per cent year on year fall of The Sun on Sunday (to 1,674,635).
The Sunday People was still selling more than one million copies a week a decade ago. In January 2000 its average weekly sale was 1.6m.
