    "I'm obviously deeply concerned to hear of the serious incident at Celsa steel in my constituency this morning. This news comes as a huge shock to the local community. 

    "I have spoken to senior management at the plant and clearly the situation is ongoing, with a number of reports of injuries.

    Mr Doughty said he visited the site a fortnight ago.

    I went outside and a PCSO said there's been a big explosion. That's all they could tell me. We heard this really loud bang. A colleague of mine, who was in the staff room, told me the ceiling shook.
