Business Secretary Sajid Javid said he was fighting for British steelworkers "every hour of the day".
Speaking on Tuesday in the House of Commons, Javid said: "Investors everywhere know British steel is the best in the world.
"They know that British steel workers are the hardest working in the world and they know that the British Government stands with the the steel industry, and we will do whatever we can to support it to become more competitive.
"The challenges we face are great, the crisis the steel industry faces is global, but I am fighting for Britain's steel workers every hour of the day.
"I was fighting for them long before this crisis hit the headlines, and I will go on fighting as long as it takes because British steel workers are the best in the world, and they deserve no less".
The Commons debate, which is scheduled to last up to three hours, has been given an emergency slot amid growing fears for the industry.
Surely David Cameron and George Osborne could not be redder than Tony Blair and Gordon Brown?
The government has indicated it would consider taking a minority stake in the UK steel business as a "last resort".
