A Dorset MP is leading a campaign to protect press freedom - a day before the Leveson Enquiry report is published.
Conor Burns, MP for Bournemouth West has signed a letter along with over 80 politicians - stating that free speech could be undermined if some recommendations from the Leveson report are adopted.
The letter was sent to The Guardian and The Telegraph, and is signed by MPs and Members of the House of Lords from all three major political parties.
The letter says: "As parliamentarians, we believe in free speech and are opposed to the imposition of any form of statutory control even if it is dressed up as underpinning.
"No form of statutory regulation of the press would be possible without the imposition of state licensing - abolished in Britain in 1695.
"Public debate will necessarily follow publication of the Leveson report and will be needed to provide confidence in a rigorous tough new system of self-regulation.
"Such a debate will lead to a speedy way of establishing a new self-regulatory regime that can restore confidence in the press."
Lord Leveson's report will be made public tomorrow.
