More than a decade after Amgen announced a €1bn investment in Cork with the promise of 1,100 jobs, the chosen site remains idle after the promise failed to materialise.

Four companies have shown strong interests in acquiring the former Amgen site in east Cork, which was once earmarked for 1,100 bio-pharmaceutical jobs.

One of the world’s leading biotechnology companies has said it has no intention of resuscitating a €820m plan to create a 1,100-job factory in Co Cork.
