Why Britain still has a mould problem - years after this toddler was killed

Kyle (not his real name) had been living in his three-bedroom house in Greater Manchester with his pregnant wife and two children for a few weeks when he first noticed the mould in the bedroom.

He wiped it away but when it returned quickly, he realised there was a serious problem.

"It spread through the bedrooms and all through the walls," he recalls. "Plug sockets used to blow because the water had gotten into them."

Clothes, toys, beds and televisions had to be thrown away.

The family ended up sleeping on the living room floor, Kyle recalls - even after his wife returned from hospital with their newborn after giving birth.
