Edward Cairney, who was convicted along with his wife Avril Jones of murdering teenager Margaret Fleming, has died in prison aged 82.

The 19-year-old, who was born with learning difficulties, went missing in December 1999 having begun living with Mr Cairney and Ms Jones in Inverclyde following the death of her father four years earlier.

In January 2000 it was claimed she had run away with a family of travellers, but social services were not aware of her disappearance.

When Mr Fleming was required to reapply for her disability benefits in 2016 due to a change in the system, it emerged that she had not been seen in close to 20 years.

Despite an extensive search of the home in which she lived no trace of her could be found.

Mr Fleming and Ms Jones were convicted of her murder in 2019 but have never disclosed where her remains were disposed of or admitted to killing her.
