BARCELONA, Spain — Catalonia’s government said more than a million voters participated Sunday in an informal vote on whether the wealthy northeastern region should secede from the rest of Spain.

The regional Catalan government pushed forward with the vote despite Spain’s Constitutional Court ordering its suspension on Tuesday after it agreed to hear the Spanish government’s challenge that the poll is unconstitutional.

The Catalan government said that over 1.1 million of the 5.4 million eligible voters had voted by 1 p.m. local time at polling stations manned with more than 40,000 volunteers.

Results are expected Monday morning.

“Despite the enormous impediments, we have been able to get out the ballot boxes and vote,” regional president Artur Mas said after depositing his ballot at a school in Barcelona.

The ballot asks voters two questions: should Catalonia be a state, and if so, should it be independent.

Polls show that the majority of Catalonia’s 7.5 million inhabitants want an official vote on independence, while around half support breaking centuries-old ties with Spain.

Catalonia’s push for independence comes two months after the Scots voted to remain in the United Kingdom.

Mas has said the vote, which lacks guarantees such as an electoral roll, is only symbolic and will likely lead to anticipated regional elections that will stand-in for a referendum on independence.

There was a festive atmosphere as hundreds lined up in front of another school in Barcelona, with some wearing pro-independence regalia.
