( CNN ) -- Far-right and far-left protest parties have dominated the crucial election in many countries across the European Union . The euroskeptics -- from the UKIP in the United Kingdom to National Front in France -- are demanding tighter border controls , nationalized decision-making and a dissolution of the currency union . There are several reasons for the surge in support , including the disillusionment of those caught in the backdraft of economic crisis and a desire by some voters to punish the political establishment . But while the euroskeptic parties are expected to claim a significant chunk of votes , their power inside the parliament will likely to be diluted by a lack of cooperation . They have little in common aside from a dislike of the Brussels bureaucracy , and a pan-euroskeptic political group is unlikely , according to political scientist Duncan McDonnell . `` The euroskeptic label covers parties of both right and left , many of whom object to the EU for very different reasons -- the radical left denounce Europe as a free-market promoting friend of high finance , while the right objects to a loss of national sovereignty and bureaucracy , '' said McDonnell , a political science fellow at the European University Institute in Florence . However , the rise in euroskeptic parties ' political clout is likely to put pressure on national governments of the member states . Five years after the financial crisis exploded , the call for change with the bloc has become louder . With protest parties coming top in several key member states , the decades-old institution could face a shake-up that will rewrite its future .
