Leave campaigners have accused the Government of trying to "bury" its own report into Britain's obligations to the EU.
The Vote Leave campaign group claimed ministers were too embarrassed by the contents of the Rights And Obligations Of European Union Membership document to highlight it.
The group's chief executive, Matthew Elliott, claimed this was in marked contrast to Government attitudes towards other reports required to be published under the EU Referendum Act.
"It's shocking that the Government has cynically buried its own report because it admits how much control we've handed to the EU. It makes clear that EU law and EU judges trump British law. The Charter of Fundamental Rights has been used by the EU to undermine our security and put up every day costs like insurance bills.
"On top of leaving EU judges in control of our borders, our economy and even those who can vote in our democracy, we hand Brussels £350 million every week." Mr Elliott said.
