One only has to have followed Catalan politics in recent years to know the importance that the composition of the board of the Parliament has taken. Debates such as those of 6 and 7 September 2017 to push through the disconnection laws, or marathon meetings on whether or not to admit a motion for a resolution under the scrutiny of the Constitutional Court, have been the focus of the political chronicles, and have given even more relevance to a vote - the first of the legislature - which for many years was seen as a mere formality that was more ceremonial than political. This time around it will be no different, and the election of the members of the presiding committee - which will have to take place on 12 March at the latest - has been playing a key role in the negotiations for the investiture for days now. What happens that day in Parliament will serve as a touchstone for the chances of success of the ERC's presidential candidate, Pere Aragonès.
