Prime Minister David Cameron said there was no guarantee that government efforts to save the British steel industry would be successful, as ministers search to find a buyer for Tata Steel's UK assets.
"There is no guarantee of success," Cameron told parliament on Wednesday.
"While I want to do everything we can to secure the future, not only for Port Talbot but also for Scunthorpe and steelmaking in Britain, we're coping with a massive oversupply, a collapse in prices, from China."
