The biggest separatist party in Spain's Catalonia region has voted to support a new Spanish government in return for talks on independence.
About 95% of members of the Esquerra Republicana de Catalunya (ERC), a social democratic party, backed the move in a ballot.
The ERC could now become kingmaker to the Socialists who failed to win a majority in this month's election.

The party is now beginning talks with the Socialists to discuss their support for Mr Sánchez, Catalan News reports.
It has a list of conditions for reaching an agreement which include holding talks without limits, including talks on an independence vote and an amnesty for the jailed leaders.
"If [the Socialists] want something from us they have to make a move," said ERC official Marta Vilalta, as quoted by Reuters news agency. "If they don't we will obviously maintain our no [vote]."
