International travel could return as soon as July.
Taoiseach Micheál Martin says the government intends to embrace the EU's digital green cert.

Pubs and restaurants can serve people in outdoors settings in groups of six, from no more than two households.
Retail stores across the North opened for the first time in around four months this morning.
