I first came across mesothelioma in the early 1970s when I was a railway manager in Liverpool. We used to stuff the boilers of locomotives full of asbestos, and of course it became widely known how lethal that was. I pay tribute to the huge efforts that have been made by the trade union movement to bring this matter to prominence. The trade unions often do not get a very good hearing in this House from various quarters, but this is a circumstance in which membership of a trade union is essential, when something like this comes across the horizon.
Could the Minister give us some idea of how many new cases are coming to light and whether there is any knowledge of which industries these come from? It would be comforting to know that this is one of the things which is getting better rather than worse.
