International travel awaits if 'dry run' between Ireland and Britain is successful

The tantalising prospect of trips to places like Barcelona could be a reality if a 'dry run' between Ireland and the UK is successful.

Ireland's common travel area with the UK could be used as a "dry run" for the EU's digital green certificate as foreign travel resumes into the summer.

The idea was first floated by Tánaiste Leo Varadkar on Thursday and cabinet sources say that while no formal proposal has been made, the idea "is one that will be looked at".
