The British steel industry was dead many, many years ago. When I moved to Sheffield (a city which, after all, has had a proud historical association with steel) FORTY-FIVE YEARS AGO, all of the 'ordinary' steel mills in the city had already been closed down. Only certain 'specialist' steels were still being made in the city (and in neighbouring Rotherham). The closures had come about through both a lack of demand for the types of steel made by those steel works and through competition from overseas (with more modern plants and lower labour costs).
Governments of both political colours had, quite rightly, recognised that there was no point trying to save uneconomic plants and hopefully, as the last remnant's of the UK steel industry breath their dying breaths many, many years after they should have done so, the current government will also follow the same line.
