Russian ambassador to Ireland 'doesn't know' if spy infiltrated Leinster House 

Russian ambassador Yuriy Filatov: Subject of Russian threat caught his attention.

The Russian ambassador has said he does not know if Leinster House has been infiltrated by a Russian spy.

It was reported last year that a member of the Oireachtas, who was given the codename Colbalt, had been ensnared within a 'honeytrap' and has been used as a Russian spy within Ireland’s political system.
