Heads of State and Government which gives too much time to summits do not
allocate the necessary time to the country's internal affairs, and this option may
cause a negative image in the society. An appropriate example is offered by Prime
Ministers Margaret Thatcher or Tony Blair who were criticized in the English press
as more and more absent (The Economist, 2001). Summits can be energizing
experience, but they have the ability to “be a drain on the participants’ energy”
(Mellisen, 2003, p. 16), especially in terms of long sessions.
