Open Europe was a British centre-right eurosceptic policy think tank with offices in London and Brussels, merging with the Policy Exchange think tank in 2020. Its stated mission was to "conduct rigorous analysis and produce recommendations on which to base the UK's new relationship with the EU and its trading relationships with the rest of the world." It promoted democratically grounded economic, trade and investment policies which foster growth, employment and freedom under the rule of law.
