Northern Ireland's Police Ombudsman Nuala O'Loan has confirmed that following an extensive investigation she has discovered no evidence that the murdered Belfast woman, Jean McConville, was a British agent.

SDLP leader Mark Durkan has welcomed the Ms O'Loan's findings.

However the Foyle MP accused the IRA of casting a slur on Mrs McConville's name and said it was disappointing that the authorities had also failed to clear her name.

Jean McConville, a widow and mother of ten, was killed after being abducted by the IRA from her home at Divis in west Belfast in December 1972.

Her remains were discovered buried on a Co Louth beach in August 2003 following a long campaign by her family.

After the IRA pledged to help families of the so-called 'disappeared', a number of searches took place in remote border areas for the remains of the 37-year-old and others.

A member of the public found her body when he was out for a walk in 2003.

At the time of Mrs McConville's death it was rumoured that she had been passing on information about local republicans to the security forces, using a secret radio transmitter.

Today, Ms O'Loan said she would give the McConvilles more details of her findings soon and will make those details public.
