A public inquiry into the murder of the Catholic solicitor Rosemary Nelson in Co Armagh almost 10 years ago has begun in Belfast.
Several hundred witnesses are expected to give evidence at the inquiry.
Rosemary Nelson was killed in March 1999, when a bomb exploded under her car outside her home in Lurgan.
Mrs Nelson had become a hate figure for loyalist paramilitaries because she had represented high profile nationalist and republican clients. Her clients included the Garvaghy Road residents who were at the centre of the Drumcree parades dispute.
Mrs Nelson received several death threats before she was killed.
An investigation by former police Ombudsman Nuala O'Loan concluded that the then RUC had disregarded Ms Nelson's safety.
The inquiry is headed by a retired English High Court judge and is expected to probe the conduct of the British security services and the RUC, among others.
It has already gathered tens of thousands of documents.
The inquiry is expected to last for at least two years.
