YES voters in Catalonia are slightly ahead of those who want to maintain the status quo, according to a new opinion poll.

The survey, from the Centre for Opinion Studies (CEO) showed 46.7% of the sample would vote yes in an immediate election while 44.9% would vote against independence.

It is one percentage point below the independence lobby’s support in a similar poll two years ago and only the second time that more people have opted for indy. The poll of 1500 voters also showed pro-indy parties would maintain their majority of 70 in the 135-seat parliament, but Together for Catalonia (JxCat) would lose out to the pro-indy Republican Left of Catalonia (ERC).

The CEO said ERC would win a Catalan election securing up to 37 seats – five more than they won in December’s election. JxCat – led by sacked president Carles Puigdemont – would win 29, down from 34.

Ciutadans (Citizens), the unionist party led by Ines Arrimadas, would no longer be the biggest party in parliament, and would lose up to seven seats and would retain up to 30 MPs. Catalonia’s Socialist Party (PSOE), led by Miquel Iceta, would increase their total to as many as 21 seats from their current 17.

The left-win Public Unity Candidacy (CUP) – the smallest pro-indy party in parliament – would increase its total from four to ten seats.

Catalonia in Common We Can, a left-wing, coalition, would also make gains to its tally of eight MPs.

The People’s Party (PP) – which was ousted from power by a

no confidence motion in the Spanish Parliament – would retain its four seats.
