Ireland
United Kingdom citizens enjoy freedom of movement in Ireland — no visa is needed and there is no fixed limit on the length of stay.
The UK government says British nationals are not legally required to show a passport to enter Ireland, but it may be useful to carry one in case they need to prove their identity, and that British and Irish citizens can continue to travel freely between the UK and Ireland under the Common Travel Area.

United Kingdom citizens can enter Ireland without a visa and live there under freedom of movement. You only need a valid United Kingdom passport at the border; immigration officers may still ask for a return or onward ticket, proof of accommodation and enough money for your stay.
Whatever your visa status, Ireland applies the same entry conditions to every traveller:
Ireland lets 75 passports in without a visa and requires an embassy visa from 123. United Kingdom citizens are treated the same way as Andorra, Austria, Belgium, Bulgaria and Croatia. Overall the United Kingdom passport ranks #29 in the world with 118 visa-free destinations.
Planning a longer trip in Europe? With a United Kingdom passport you can also visit 45 countries in the region without a visa, including Andorra, Albania, Armenia, Austria, Bosnia and Herzegovina, Belgium, Bulgaria and Belarus.

No non-national may be in the State other than in accordance with a permission given by or on behalf of the Minister; one who is in the State in breach of this is unlawfully present. The Minister may make a deportation order against a person who, in the Minister's opinion, has broken a restriction or condition of their landing, entry or leave to stay. The order requires the person to leave the State within the period it sets and to stay out of the State afterwards.
