A British Home Office consultation paper has issued a proposal today to introduce border checks between Britain and the Irish Republic for the first time in more than 80 years
This could include full passport checks the Home Office consultation paper said.
The checks would apply to those travelling by air and sea between Britain and Ireland but could also include immigration checks at the UK border within the island of Ireland.
However, both governments have said that there are no plans for checkpoints to be re-introduced along the border.
The scheme is proposed to target illegal immigration by non EU nationals rather than UK or Irish citizens.
The commona travel area which was established in 1925 includes Ireland, the UK, the Isle of Man and the Channel Islands. The paper also proposes increasing checks for travellers to these destinations.
The paper also suggests that laws could be proposed to allow searches of vehicles travelling to and from the Irish Republic which could indicate proposed seraches at the border.
