Brussels - European Union leaders Thursday agreed on a series of concessions allowing Ireland to hold a new referendum on the stalled Lisbon Treaty in the autumn of 2009, EU diplomats said.

Irish voters rejected the treaty in a referendum on June 12, meaning that it cannot come into force anywhere in the bloc unless a second referendum overturns that decision.

The concessions agreed on Thursday include allowing each member state to nominate a member of the European Commission beyond 2014. (dpa)
