The news that four phone hacking cases have been lodged at the High Court against Mirror Group Newspapers raises the troubling possibility that hacking went beyond News International.
It is important that allegations of phone hacking or other criminality in any news organisation are taken seriously.
Former Blackburn Rovers footballer, Garry Flitcroft, is one of four people who are taking legal action against Mirror Group Newspapers for alleged phone hacking.
In November, Flitcroft told the Leveson Inquiry that he had previously been hounded by tabloid media in 2001 over an extra-marital affair.
As news emerged that four people have issued hacking claims against Mirror Group Newspapers, its owner Trinity Mirror's shares fell 12% today, reversing some of the recent strong gains for the stock.
Shares in the group were down 12 percent at 63 pence at 0725 GMT, according to Reuters.
Johnathan Barrett, an analyst at N+1 Singer, said:
The shares have been very strong and buoyed by an improved nationals advertising market and the likelihood of greater cost savings in 2013.
The claims will weigh on the shares, in part because many had assumed the subject was fading away as an issue.
Former England football manager Sven-Göran Eriksson – has filed a claim alleging phone hacking at the Daily Mirror during Piers Morgan's editorship.

There is evidence which is going to be put forward. This is the very start of a claim and allegations are going to be put forward... The Mirror Group might say they don't know but the allegations for example against Sven Goran Eriksson have been made public... There has always been a continual mantra [by the Mirror Group] by saying 'we always comply with criminal law and have always complied with the Press Complaints Commission code'. The courts will investigate the evidence.
