The role of the national Parliaments in scrutinizing the governments’ actions has been in the academic agenda for a long time. The paper will examine the parliamentary response, in terms of parliamentary control, on the governmental negotiations for three Economic Adjustment Programmes for Greece in the time period between 2010 and 2015. In an additional case study, the parliamentary means in the National Assembly of Serbia will be examined in the light of the opening of the negotiation process with the EU. In both cases, an overview of the available means of parliamentary control will be presented, followed by a discussion of their suitability to exercise control of governmental actions in the European organs. Specific cases of parliamentary control will also be presented, as well as relevant statistics.
