The Unite union has been given until May 21 to decide whether to accept a new deal, hammered out today after 12 hours of talks.
As I said last time, the details of the proposals are confidential until the parties report back to their respective organisations.
After that the detail may be disclosed by the parties themselves.
Acas would like to thank the parties for their commitment, hard work and patience during the course of these difficult negotiations and hope that these proposals will lead to a successful outcome.
