of the Parliament of Catalonia expired four years after the date of its previous election, unless it was dissolved earlier. The regional president was required to call an election fifteen days prior to the date of expiry of parliament, with election day taking place within sixty days after the call. The previous election was held on 19 November 1995, which meant that the legislature's term would have expired on 19 November 1999. The election was required to be called no later than 4 November 1999, with it taking place on the sixtieth day from the call, setting the latest possible election date for the Parliament on Monday, 3 January 2000. The president had the prerogative to dissolve the Parliament of Catalonia and call a snap election, provided that no motion of no confidence was in process and that dissolution did not occur before one year had elapsed since a previous one under this procedure. In the event of an investiture process failing to elect a regional President within a two-month period from the first ballot, the Parliament was to be automatically dissolved and a fresh election called. Parties and candidates The electoral law allowed for parties and federations registered in the interior ministry, coalitions and groupings of electors to present lists of candidates. Parties and federations intending to form a coalition ahead of an election were required to inform the relevant Electoral Commission within ten days of the election call, whereas groupings of electors needed to secure the signature of at least one percent of the electorate in the constituencies for which they sought election, disallowing electors from signing for more than one list of candidates. Below is a list of the main parties and electoral alliances which contested the election: Opinion polls The tables below list opinion polling results in reverse chronological order, showing the most recent first and using the dates when the survey fieldwork was done, as opposed to the date of publication. Where the fieldwork dates are unknown, the date of publication is given instead. The highest percentage figure in each polling survey is displayed with its background shaded in the leading party's colour. If a tie ensues, this is applied to the figures with the highest percentages. The "Lead" column on the right shows the percentage-point difference between the parties with the highest percentages in a poll. Graphical summary Voting intention estimates The table below
