This study explores the powers of the EP and six selected national parliaments (the British, Danish, French, Irish, Italian and Polish) in setting, amending and scrutinising budgets. It then considers European engagement in three conflict regions – Libya, Palestine and Afghanistan – assessing how the selected parliaments have overseen various aspects of foreign policy, including finance for core activities and responses to sudden crises, and considers whether there are possible synergies between national and European budgets in foreign policy broadly defined.
