British Airways owner International Airlines Group (IAG) looks set to take over Aer Lingus after the Irish government gave the green light to a £1.03 billion bid.

The Dublin administration, which owns a quarter of the national airline, say they are supporting the proposed deal after seeking reassurances and commitments.

Transport Minister Paschal Donohoe said: "IAG has provided additional information and certain commitments in relation to its proposal," he said.

"Following detailed consideration of this and all of the issues surrounding a potential disposal of the State's shareholding in Aer Lingus, the Government has decided that it will support IAG's proposal."

IAG said it has agreed to a number of legally binding promises on the future of Aer Lingus, including the development of the Irish capital as a transatlantic hub.

It vowed that Aer Lingus will remain headquartered in the city, keep existing slots at Heathrow, continue routes between the London airport and Dublin, Cork and Shannon for the next seven years, as well as retaining its corporate brand.

Up to 635 new jobs will be initially created at Aer Lingus.

The Dail, Ireland's parliament, will now vote on the proposals.
