The Catalan National Assembly, with about 30,000 fee-paying members, called the rally to lobby 10 lawmakers from the far-left CUP group to set aside differences with 62 parliamentarians from the "Together for Yes" alliance and break a logjam that is paralyzing progress toward an independent Catalonia, the Associated Press reported on Monday.
The parliament of Catalonia has until Jan. 10 to elect a leader and form a government or it must call a new election.
With 72 seats, pro-secessionists would hold the majority in the 135-seat regional parliament, although they only secured 48 percent of the popular vote in September elections.
