One bereaved father told the BBC that his son was killed "in cold blood".

More than 36,000 people have signed up to one such petition, led by two sets of bereaved parents; while campaign group Maternity Safety Alliance is making a similar call.

Justice Minister Naomi Long said the aim is that Charlotte's Law will build upon the work of Helen's Law and help bereaved families in Northern Ireland.

The inquiry has heard from hundreds of witnesses, including current and former politicians, civil servants, government advisers, public health experts and representatives of bereaved families.

"I share everyone's frustration that this has taken too long - survivors, bereaved families and all those who have campaigned for truth and accountability deserve better," she said.
