Deputy Prime Minister Nick Clegg has urged Britain's leading newspapers to support the politically-endorsed press regulation deal and recognise its benefits.
"The whole design of Leveson was based on ... independent self-regulation, but with a number of incentives which make it worth newspapers actually joining in the system," he said.
The Liberal Democrat leader appealed for editors and other influential media figures to recognise the benefits of the proposed new regulatory system, saying:
I hope that when they examine the fine print, they will see that the incentives are strong and that it's worthwhile, not least in order to restore public trust in the conduct of newspapers, for them to join in with the system, and I very much hope they will.
David Cameron has insisted a cross-party agreement for a new system of press regulation protects the principle of the free press.
Labour says this is just the sort of legal under-pinning they were looking for but the Conservatives say that no such press law will exist.
Is there a chance tomorrow's Commons' votes on press regulation may not go ahead? Could there be agreement between the parties after all?
