US based institutional shareholder Tweedy Browne was one of the leading groups pushing for the sale of the Daily Mirror and titles including the Sunday Mirror last year, arguing that there was no synergy between them and Trinity's stable of profitable regional titles.
No sale transpired, however Tweedy Browne's insistence that further questions need answering surrounding this latest scandal, is likely to push a possible change in ownership further up the agenda.
Tweedy Browne, which owns about 4% of Trinity Mirror shares, along with other shareholders such as ISIS Asset Management and Deutsche Asset Management specifically want to know how the pictures got through the Daily Mirror's system of editorial controls.
Since it emerged that photographs of alleged abuse by UK troops against Iraqi prisoners were fake and the subsequent sacking of editor Piers Morgan the price of Trinity Mirror shares have taken a slight knock, down 1.38% to 606.5p a share today.
When Bailey took over the role at the start of last year she refused to rule out the sale of the national titles saying the board would keep an open mind about any possible bids.
She has come in for criticism of her own during the Iraqi picture scandal with commentators saying that the lack of a strong proprietor allowed the scandal to happen more easily.
