At lunchtime on Sunday, Hacked Off’s online petition calling on the main party leaders to implement the Leveson recommendations on press regulation in full passed 100,000 signatures. People continue to sign and the number is climbing so rapidly that this may be Britain's fastest-growing online petition ever.Professor Brian Cathcart, Director of Hacked Off, said:

This is a powerful indication of the strength of public feeling on Leveson.We have long known that the public is firmly behind effective, independent regulation of the press, which is what the Leveson Report recommends.We hope that the Prime Minister, who last Thursday appeared to reject a key part of the recommendations, is listening to the voice of the public, just as he promised he would in his evidence under oath at the Leveson Inquiry.He also promised to listen to the voices of people who have suffered from press abuses, and they have clearly stated their approval for the Leveson proposals.

The House of Commons debates the Leveson Report tomorrow and Hacked Off is calling on all MPs to stand up to press bullying and propaganda and ensure that self-regulation is guaranteed by law to be independent and effective, as the judge has declared is essential.There must be no fixes or fudges, and no more last chances for editors and proprietors who have been found guilty by the Leveson Inquiry of causing devastating harm to the lives of innocent people.Hacked Off has robust procedures in place to ensure that the petition results are not open to abuse. A continuous process of verification is under way and false or repeat signatures, where found, are removed from the total number given on the website. We have uncovered very little evidence of such abuses.
