It's the most dangerous employment sector, so why have safety inspections on building sites plummeted?

There's been an alarming cut in the number of unannounced inspections by the Health and Safety Executive on construction sites, Unite the union is warning.

Construction is the most dangerous employment sector, with 30 deaths at work reported last year and the most common type of fatal accident being falling from a height.

Now Unite has obtained figures through a Freedom of Information request showing that the number of proactive HSE inspections has fallen from 11,303 in the year 2013/14 to 7,793 last year, a 31% drop.
