Proměny postavení Evropské lidové strany v Evropském parlamentu

The thesis is a study devoted to the changes of the Group of the European People's Party in the European Parliament (EPP) with focus on the situation after election in 2009. The main aim of the thesis is to find an answer to the question, whether the position of current EPP has been weaken after the election of 2009 and after the split of ED. This is reached through comparison current EPP's position with its position in legislative period 2004 -- 2009. In order to verify or to disprove this question we apply various points of view. First, we analyze historical development of political groups and their legal conditions. Afterwards, we deal with development of EPP Group to its current form and define its fundamental characteristics. The basis for the analysis of change of EPP's position after election in 2009 is the description of the EPP's situation after this election. We compare the position of EPP (EPP-ED) in both mentioned periods by means of four indicators (size, number of mandates, occupation of key posts, coherence and loyalty in voting and ability building coalitions). Resulting evaluation of single indicators provide us with the answer to the question, how the EPP's position has changed after election in 2009.
