The Remain camp is right that Brexit would be likely to lead to a hardening of the border between Northern Ireland and the Irish Republic.
The UK and Ireland are part of a Common Travel
Area with the Isle of Man permitting freedom of movement between them. But if
there was a Brexit, their shared membership of the EU would end and with it
common agreements on migration, especially EU migration.
Brexit campaigners claim Britain can secure its
border and restrict EU migration by leaving the EU. Their promise that there
would not be any border controls on the ground with Ireland are a direct contradiction.
They cannot promise to restrict EU migration better while leaving an open,
unrestricted border with a EU country – EU migrants could simply enter Britain
through this backdoor.
Either Brexit campaigners have not thought this
through – or they forget that Northern Ireland is every bit a part of the UK as
England, Scotland or Wales.
