The majority of local newspaper editors believe cost amendments to the Data Protection Bill would lead to more titles closing, as MPs prepare to vote on two “anti-press curbs” proposed by Labour tomorrow.

Ninety-two per cent of editors surveyed said they do not believe another Leveson-style inquiry into the media should take place, while 69 per cent thought some local newspapers would close if the cost amendments became law.

MPs will vote tomorrow on an amendment to the Data Protection Bill tabled by former Labour leader Ed Miliband, which would establish a broad new statutory inquiry into data protection issues in the media after the Government scrapped the second part of the Leveson inquiry.
