The Republic of Ireland appears to have got the virus under control with daily new cases generally in single figures, or the very low teens. I can understand why the experts there might consider that the best way to keep it that way is to avoid foreign travel. Then one wonders why unfettered travel is still allowed between the Irish Republic and the UK, where the virus is far from under the same level of control and Ireland.
It is noticable that the government north of the border appears to be following the RoI lead rather more closely than it is the Westminster one.
