"We do not trust the official results and are fearing fraud, therefore we will hold our own count," the spokesperson said.
In order to do this, the assembly will collect data from the observers of three political parties that share the idea of Catalonia's independence from Spain. The assembly said observers were present at all polling stations.
Approximately 4,000 observers are involved in the elections and are now submitting data on the turnout to the assembly.
"We are getting the data during the day… Right after the closure of polling stations, our center will start receiving official information from there," the spokesperson noted.
The assembly's vote count results will be announced in Barcelona's Maritime Museum and reporters and foreign observers are invited to attend.

The assembly cooperates with such political parties as Together for Catalonia (Junts per Catalunya), the Republican Left of Catalonia (Esquerra Republicana) and Popular Unity Candidacy (CUP).
Earlier in the day, polling stations opened across Catalonia to elect the region's legislative body in the snap election called by the Spanish government. The Spanish authorities dissolved the regional parliament in response to a resolution on the region's independence, adopted on October 27.
The 2017 regional elections that are scheduled on December 21 were called by Prime Minister Mariano Rajoy after the invocation of Article 155 of the Spanish Constitution of 1978, imposing Madrid's direct rule over Catalonia.
