PSNI 'has questions to answer about Donaldson killing'

Sinn Féin has claimed the PSNI Special Branch has serious questions to answer about the murder of Denis Donaldson.

The party made the claim following media reports that the man who led a Sunday newspaper to the 55-year-old's home in Co Donegal was a former member of the RUC.

Mr Donaldson was a leading Sinn Féin official until he admitted last year that he had been a British spy since the 1980s.

He was shot dead three weeks after a Sunday newspaper exposed the isolated cottage near Glenties where he had been living since his admission.
