Victims of phone-hacking and press intrusion said they felt "betrayed" by British Prime Minister David Cameron after he warned against legislation to underpin regulation of newspapers.
The Hacked Off campaign had welcomed Leveson's proposal. But its leader, Brian Cathcart, said Christopher Jefferies, an innocent murder suspect who gave evidence at the inquiry, "feels betrayed".
Mark Lewis, a lawyer for the Dowler family - whose murdered teenage daughter Milly's phone was hacked by the News of the World - said a return to a system of self-regulation would be a backward step .
He said: "There wasn't much point in a judicial inquiry unless it's implemented. It's snakes and ladders. We're going back down to where we started from."
Ed Blum, a film director whose phone was hacked, said Cameron had "ripped out the heart and soul" of the report.
"He's let down the victims of press abuse," Blum said.
