criticised by MEPs such as the ALDE group leader Graham Watson who described the procedure as a "Justus Lipsius carpet market" producing only the "lowest common denominator"; while Green-EFA co-leader Daniel Cohn-Bendit asked Barroso after his first speech "If you are the best candidate, why were you not the first?" Criteria The candidate selected by the Council has often been a leading national politician, but this is not a requirement. The choice of President must take into account the result of the latest Parliamentary elections (for example, by choosing the candidate supported by the largest European political party in particular, or at least someone from that political family the Spitzenkandidat principle, below but this is a convention, not an obligation). That provision was not in force in the nomination in 2004, but the centre-right EPP, which won the election, pressured for a candidate from its own ranks. In the end, the EPP candidate, José Manuel Barroso, was chosen. On the same basis, the EPP endorsed again Barroso for a second term during the 2009 European election campaign and, being largest again after that election, was able to secure his nomination by the European Council.

There has been an assumption that there is a rolling agreement along these lines, that a president from a large state is followed by a president from a small state, and one from the political left will be followed by one from the political right: Roy Jenkins (British socialist) was followed by Gaston Thorn (Luxembourgish liberal), Jacques Delors (French socialist), Jacques Santer (Luxembourgish Christian democrat), Romano Prodi (Italian left-wing Christian democrat) and Jose Barroso (Portuguese Christian democrat).
