Such measure will be taken in response to alleged personal threats over the last few months.
The Taoiseach has been advised to change the route he takes to and from Government Buildings daily, and Ministers will now have to provide the Gardai with details of their work schedules.
Some additional measures may be extended to members of the Gardai themselves, after it became known that a female garda was followed home last week.
The security arrangements for President Michael D Higgins are also being reviewed, after an incident in Finglas last week where a group of protesters surrounded his vehicle and branded him a ‘traitor’ for signing the Water Services Bill into law.
