Ivan Lewis MP, Labour's Shadow Culture, Media and Sport Secretary, said:
"This shocking news about the hacking of Sara Payne's phone will ignite anger and revulsion across the country.
"The newspaper which championed Sara's campaign for Sarah's law invading her privacy in such a cruel way, raises further serious questions about what was happening at the News of the World on Rebekah Brooks' watch.
"It also casts a further shadow over David Cameron's judgment in employing Andy Coulson. He and George Osborne have failed to provide full and frank answers."
