An Essex MP has called for an inquiry into the administrative proccess surrounding the closure of the Coryton Oil Refinery.
Basildon and East Thurrock MP Stephen Metcalfe raised the issue in the House of Commons.
Administrators announced the plant would close when a new buyer couldn't be found.
900 jobs are affected.
Mr Metcalfe told the House "The closure of Coryton was obviously not the outcome I fought for and the announcement was one that I had hoped never to hear.
"I believe it represents a sad day for the refining industry in the UK, a sad day for South Essex and above all it was a devastating blow for the hundreds of dedicated workers who have fought so hard to keep the refinery open."
It's been announced that Coryton oil refinery will close. Glen Goodman has been looking at the future for the workforce and been speaking to Stephen Metcalfe, the MP for South Basildon and East Thurrock.
Coryton Refinery was plunged into administration by its Swiss owner Petroplus in February. It has been reported that a tanker reached the plant last week with enough crude oil to keep the site working for 11 days but the plant is unlikely to carry on operating beyond the end of this month.
