The national broadcaster has apologised after a number of its top stars were photographed next to each other at a “short, impromptu” party.
In a statement, RTE said said it takes public health advice “with the utmost seriousness and has implemented detailed workplace protocols which have been in place since the beginning of the pandemic”.
“These have been essential in keeping staff and visitors/programme guests safe whilst on site.
“Because of the measures taken by RTÉ, no cases of Covid-19 have so far been transmitted on campus.”
It added: “RTÉ and those involved regret this occurred.”
“Over the last few days we have reminded all staff of their obligations to keep both themselves and the site safe, particularly over the very busy few weeks we are heading into.”
Hosts including Bryan Dobson, David McCullagh and Miriam O’Callaghan were among attendees at an “impromptu gathering” for colleague Phil Collins.
