 For example, in some parties, the parliamentary and organisational leadership will be held by the same person or people, whether "ex officio" or not; other parties maintain a sharp distinction between the two offices.Nevertheless, in almost all cases, the parliamentary leader is the public face of the party, and wields considerable influence within the organisational wing, whether or not he or she has any official position there.A parliamentary group is typically led by a parliamentary group leader or chairperson, though some parliamentary groups have two or more "co-leaders".
