A book and a film are certain to follow the conviction of a brutal murderer who 17 years strangled a 22-year-old woman. Twice a jury failed to convict him and the labourer was acquitted.

But it was the gritty determination of the woman’s broken-hearted mother to see justice done – forcing a change in the double jeopardy law – that led to Billy Dunlop finally being jailed for life. It was the first double jeopardy conviction in the UK for 800 years.

Dunlop had later boasted about his killing in jail while serving time for assault, but the law then did not permit him to be re-tried for the murder.

Ann Ming could not sit by and do nothing. She had discovered her daughter’s body behind a bath panel months after police had failed to find it. It was an indescribable shock which shattered the lives of her family forever.

She campaigned for the change in law, she even had to petition the House of Lords, but nothing was too daunting for her.

I hope her courageousness will be marked in some way, she should be awarded some recognition, but I suspect seeing her daughter’s killer jailed for life was “reward” enough. I wonder how many other similar trials will follow.

Love and a desire for justice is the most powerful force, Ann Ming is certainly my Woman of the Year.
