THE Home Secretary and other major politicians are to receive a copy of a documentary detailing a North-East mother's campaign for justice for her murdered daughter.

It's My Story: The Man Who Killed My Daughter, will be broadcast on Radio Four tonight, at 8pm.

It tells the story of Teesside mother Ann Ming and her campaign to change the law so that Billy Dunlop, the self-confessed killer of her daughter, can be convicted.

A jury twice failed to convict Dunlop, from Billingham, of the murder of the mother-of-one, Julie Hogg. Later, while serving a prison sentence for another offence, he admitted the crime.

Because of the double jeopardy law he could not be tried again and, instead, was sentenced to six years for perjury.

Since then, Mrs Ming and her husband, Charlie, have campaigned, alongside The Northern Echo, for a change in the law so that, in exceptional circumstances, someone can be tried more than once for the same crime.

The documentary tells Mrs Ming's story and her fight for justice and includes The Northern Echo's involvement in the case.

The show's producer, Mark Handscomb, has pledged to send copies of the programme to Home Secretary David Blunkett and other politicians who have failed to back a change in the law.

There are less than 20 cases across the country where a law change could lead to a conviction, but Julie Hogg's is the only one that concerns a self-confessed killer.

The Law Commission has also called for the double jeopardy rule to be scrapped in certain cases and it is hoped the Government's Law Reform Bill, published later this year, will follow this recommendation.
