Multifarious than 1,000 jobs are to go at Tata Steel plants, mostly in south Wales.
Tata suggested 750 jobs would go in Port Talbot, while 200 supporter staff elsewhere would be axed.
Other job losses would take in 15 at Trostre, Llanelli along with jobs going at Hartlepool in north east England and at Corby, Northamptonshire.
It told “tough actions are critical in the face of extremely difficult market states”.
Karl Koehler, chief executive of Tata Steel’s European undertakings, said: “We need the European Commission to accelerate its response to unfairly bought imports and increase the robustness of its actions. Not doing so threatens the future of the total European steel industry.
“And while we welcome progress on UK energy yments, the (UK) government must take urgent action to increase the competitiveness of the UK for its compulsory steel sector.
“This includes lowering business rates and standing energy efficiency and anti-dumping cases so we can compete fairly.”
Stuart Wilkie, hub director of Tata UK’s strip mills division, claimed they were taking the necessary steps to keep the 3,500 burglaries remaining jobs in Port Tabot but still needed help.
“Affirm aid or rt nationalisation isn’t the way forward,” he said.
“We want a level fritz field that we can compete on our own two feet in the European and global market dispose.”
He believed they could turn it around but could not say Monday’s job dyings were enough to secure the plant or satisfy Tata bosses in India.
“I couldn’t get off off anything. The challenge is we need the workforce and ourselves as managers to respond to the dares if we’re to sustain a long term future for the plant in Port Talbot.”
Prime Minister David Cameron said: “We’ll sweat very closely with the com ny, with the local communities to do the total we can, to get people the training and the assistance they need.
“And we’ll continue to help the sword industry.”
Labour said the UK Government had delivered “little concrete effectiveness” but Business Minister Anna Soubry insisted it had responded to many of the on request on calls from the steel industry and was creating a “level playing field” such as clipping energy costs.
First Minister Carwyn Jones described the job reject a deletes as a “devastating blow” to the community and the wider economy.
Earlier, Community accepted secretary Roy Rickhuss called for “meaningful action” from the UK government.
Penurious Chinese imports, a strong pound and high energy costs bring into the world been called “a perfect storm” for the UK steel industry.
Mr Rickhuss totaled: “The dumping of cheap Chinese steel is one of the biggest causes of this moment, yet the UK government remains a cheerleader for China and their bid for ‘market economy station’, which would decimate what’s left of our steel toil. This cannot be allowed to happen.”
But he called for long-term commitment to nerve making in the UK from Tata after “significant sacrifices” from its workforce.

The steelworks have been rt of the scene in Port Talbot for decades. It is the biggest flower in the UK, providing well id jobs that are difficult to replace. For every job in the steelworks, it is estimated another four asses in the local economy are supported.
This is another bitter blow for the Tata station and an industry that has been struggling and a workforce that has put a lot in, in recent years, to try to scram Tata competitive.
But it is fighting against global forces including cheaply imports from China. The UK government has put in measures recently to deal with luxurious energy costs but the industry has been calling for these for four or five years.
The blade industry has not really recovered from the financial crash in 2008 when at its extreme fell people stopped buying white goods, cars, and construction stopping up. We talk a lot about dumping but it is cheaper to produce steel in China and that is not effective to change.
Tata have invested quite heavily in Port Talbot with the new lay waste furnace in rticular and also in the workforce and it has been quite tient.
But essentially the concern is that tience will eventually run out. We are looking at a meeting at Tata headquarters in India in a few weeks time again and the com ny will look at the proposals made by Tata UK and may think that is a upper crust case scenario and does not go far enough.

Andy Richards, Glue Wales secretary, said steel “runs through the heart of the Welsh conservatism”.
He added: “Job losses on this scale will reverberate Sometimes non-standard due to the supply chain, communities and associated industries across Wales.”
The Alliance of Small Business described the losses as a “a hammer blow”.
Tata Fortify employs more than 80,000 people worldwide and is rt of the wider Tata Unit, an Indian conglomerate.
