A major security and policing operation is under way in Dublin for the arrival of UK Prime Minister Keir Starmer and the international soccer match between Ireland and England.
All garda leave and rest days in Dublin have been cancelled and 400 public order officers will be on duty.
Additional gardaí have also been called in from outside Dublin.
Keir Starmer is due in Dublin tomorrow for intergovernmental talks before attending the match at the Aviva Stadium tomorrow evening following an invitation from the Taoiseach two months ago.
Police officers from the UK's football intelligence unit which has been working closely with gardaí over the past few months have now arrived in the city.
They will work from the garda control rooms, monitoring CCTV and looking out for known UK football hooligans and troublemakers who have been banned from international travel and should not be in Ireland.
They are here in a support and advisory capacity and have no policing powers.
They may also accompany gardaí on the streets if it becomes necessary for them to identify known troublemakers to them.
The match has been declared "an extraordinary event" in Dublin.
Garda Headquarters said today it is not anticipating trouble but is prepared for it.
Patrols will begin around the Temple Bar and city centre areas this evening and there will be a substantial policing and security presence around the Aviva Stadium tomorrow.
Gardaí say they have no evidence at this stage of any large scale organised or pre-planned campaign to cause trouble.
The Garda Commissioner Drew Harris said the far right "is not on our radar" at the moment.
The vast majority of fans in the stadium are Irish ticket holders.
Around 3,000 English fans have been allocated tickets and gardaí do not expect large numbers of other fans to travel to Dublin.
