The European Parliament is regarded as weak for several reasons: it is too large with 785 members divided along political, national, and regional lines lacking coherence; the executive Council and Commission are not drawn from Parliament so decision-makers do not rely on its support; and MEPs have limited authority and knowledge of complex EU issues. However, Parliament is getting stronger through treaties granting it more legislative power, better organized political groups, and increased accountability of the Commission. Parliament has flexed its muscles by rejecting Commission nominees and extending its influence on human rights, the single market, and other policies.
