Steelworkers from all over the country have demonstrated in Sheffield over cuts to Britain's ailing steel industry.
Thousands of job cuts have recently been announced in Teesside, Scunthorpe and Lanarkshire, with unions fearing more to come.
The TUC-organised rally urged the government to stem the influx of cheap steel from China.
Business Minister Anna Soubry said her department was doing all it could.
TUC general secretary Frances O'Grady said: "The crisis in British steel isn't over. One in six steelworkers face losing their jobs.
"Britain desperately needs a long-term industrial plan, but ministers have refused to commit to one.
"The closure of factories will devastate surrounding communities, and cause jobs losses throughout the supply chain. The chancellor's 'Northern Powerhouse' has to be more than a slogan for a party conference."
