Brexit secretary David Davis has been threatened with legal action because of his refusal to release 50 government commissioned studies on the impact of leaving the EU.
Lawyers for the Good Law Project have written to the Department for Exiting the European Union demanding the documents be published.
The project’s lawyers said if the studies, which look into the effects of Brexit on different industries, are not released within two weeks they will begin judicial review proceedings before the high court.
Green MEP Molly Scott Cato, who is bringing the action alongside the Good Law Project, said: “The European referendum was all about taking back control but how can our democratic representatives make decisions in our interests when the government is withholding vital information?”
“It has been clear for some time that the attempt to keep the Brexit impact studies secret is more to cover the government’s blushes than to enable efficient lawmaking.”
A letter demanding Davis release the findings has been signed by more than 120 MPs.
