The families of two children from Hertfordshire, who died after they got tangled in blind cords, have launched a safety campaign against the danger.

An inquest has ruled that 2 year old, Emily Warner from Royston, died in a "tragic accident"

She died just months after toddler Arthur Winfield lost his life at his home in Markyate.

I spoke to Emily's father Jamie at Hatfield Coroners Court.
