The powers of the executive arm of
government which is responsible for the implementation, execution or
enforcement of laws, policies and directives
made and given by the legislative arm of government
have increased in recent years as
a result of the following reasons:

  1. The power to veto acts of parliament granted to the president who is the head of the executive
    has helped to increase the powers of the
    executive.
  2. The exercise of prerogative of
    mercy by the president has; contributed in increasing
    the power of the executive arm of government in recent years. 
  3. The principle of delegated
    legislation has made it possible, for members of the executive to involve in
    law making, thereby increasing their powers.
  4. The power granted the president
    to name all federal judges  goes a long way in increasing the power of the executive arm of government. 
  5. Through the exercise of prerogative of
    mercy by the president, he interferes in the functions of
    the judiciary which has contributed in increasing the powers of the executive arm of government.
  6. By taking part or belonging to
    administrative tribunals which are equally set up by the executive,
    members of the executive perform quasi judicial duties which
    have gone a long way in increasing their
    powers.
  7.  In
    period of emergency, the executive appoints administrators many of
    whom come from executive arm of government who perform both executive and legislative functions.
