(Corrects to show statement from Socialists, not joint statement)
MADRID, Nov 28 (Reuters) - Spain's Socialists said on Thursday they had a "constructive dialogue" with the Catalan separatist party Esquerra Republicana de Catalunya (ERC) during their first official meeting to negotiate the formation of a new Spanish government.
In a statement issued after the 2-1/2-hour meeting, the party spoke of differences but also of a joint determination to continue talks to allow the formation of a government and ensure political stability.
A further meeting would take place on Dec. 3. (Reporting by Jessica Jones; editing by James Mackenzie and Sandra Maler)
