LONDON (Reuters) - The union at Scotland's Grangemouth refinery has offered a two-year no-strike deal in a bid to persuade its owners not to close the site, local Member of Parliament Michael Connarty told Reuters on Friday.

Ineos, which has said it will close a petrochemical plant on the same site and has threatened to close the 210,000-barrel-per-day refinery, is expected to make a statement soon about whether it has accepted the union's offer to go along with a survival plan.
