@Walter Hinteler,
According to a report in
The Guardian, Ireland is hoping to seal a special Brexit side deal in Brussels allowing it to continue using the UK as a “land bridge” for goods in transit to Dublin without border checks, a senior Irish tax official has revealed.
Under the special deal being discussed, goods from the continent would undergo checks in Calais. The freight containers would then be sealed and given free passage to Dublin via Dover and Holyhead.
