More than €1.6 million has been spent fitting or upgrading security systems at the homes of politicians and other officeholders since the start of last year.
There has been a significant rise in expenditure by the Office of Public Works (OPW) over the past eighteen months against the backdrop of the growing threat from far-right activists and extremists.
The latest figures show the OPW paid out €809,000 for security systems at the private residences of eleven individuals in the first six months of this year.
Details of which politicians and officeholders are involved are not provided on the basis the information could be used by right-wing extremists or criminals.
However, it is known that works generally relate to at-risk Oireachtas members, ministers, judges, officials of the Criminal Assets Bureau, and former officeholders like Taoisigh or ex-Presidents.
Security concerns for politicians have grown dramatically over the past three years with masked protests outside some homes and bomb threats made against Justice Minister Helen McEntee and Taoiseach Simon Harris.
Asked about the expenditure, the OPW said: “We do not have any further comment to make at this time.”
