Before 1993, Andorra's political system had no clear division of powers into executive, legislative, and judicial branches. A constitution ratified and approved in 1993 establishes Andorra as a sovereign parliamentary democracy that retains the president of France and bishop of Urgell as co-princes and heads of state. However, the head of government retains executive power. The two co-princes serve coequally with limited powers that do not include an individual veto over government acts (however, a bill can in effect be "vetoed" if both do not sign the legislation). They are each represented in Andorra by a personal representative.
