The family will meet Alex Davies-Jones, Minister at the Department of Justice.

Several families affected by the Legacy inquiry had planned to go to Parliament.

However, in a letter to the families, Hardy said Humberside Police and the Crown Prosecution Service had raised concerns about the attendance of potential witnesses and asked him to rearrange the visit.

Hardy said they agreed to have only one family attend.

Mr Essex and Ms Stockdale will pass messages to the minister from other families, including Billie Jo Suffill.

Ms Suffill lost her father, Andrew, and brother, Dwane, within five days of each other in July 2022, and used Legacy for their cremations.

She said she still hadn’t received her father’s ashes and was worried she had the wrong ashes for her brother.

In July, Humberside Police confirmed officers had contacted 163 families linked to ashes recovered from Legacy Independent Funeral Directors. Ms Suffill has not been contacted.

The mother-of-three said it was “absolute torment” not knowing where her father’s ashes were.

“It could be on someone’s mantle, in someone’s necklace,” she said. “I’ll never know.”
