Pro-independence party Junts per Catalunya was seen winning 25-26 seats, ERC another 32 seats and extreme-left party CUP 9 seats, according to the poll carried out by Sociological Research Centre (CIS), Reuters reported.
That would give the pro-independence camp just 67 seats in the 135-seat regional parliament, stripping them of the previous slim majority.
The government's People's Party (PP) would win just 7 seats while the Socialists would take 21 and the market friendly Ciudadanos 31-32 seats, the poll showed. CatComu-Podem, the Catalan arm of the anti-austerity Podemos party, could win 9 seats, according to the survey.
