The press must be set a deadline to implement Lord Justice Leveson's recommendations, according to campaign group Hacked Off.
The group, which represents victims of press intrusion, said the Leveson report proposals were "reasonable and proportionate" and should be implemented as soon as possible.
Former Crimewatch presenter and police officer Jacqui Hames, a victim of phone hacking, read out a statement on behalf of Hacked Off.
She said: "The judge had rightly condemned this outrageous conduct of the press in the recent years.
"The crucial point is the importance he places on the complete independence of regulation from politicians and from the editors and proprietors, who run the wholly discredited PCC.
"He has proposed a system of voluntary and independent self-regulation.
"The proposals made by the industry do not come close to this ideal.
"What is needed is a regulator which can properly and effectively protect the victims of press misconduct.
"He has recommended that this be backed by legislation to protect the public and the press.
"These proposals are reasonable and proportionate and we call on all parties to get together to implement them as soon as possible.
"The press must be given a deadline, the inquiry is over, now is the time for action."
