The Cabinet will consider a proposal later today to make the wearing of a face covering compulsory on all forms of public transport.
Under the memo to be brought by Minister for Transport Shane Ross, the two-metre physical distancing rule would no longer apply and, in tandem, capacity on buses, trains and trams could be increased to 50%.
The Cabinet will not decide today what approved EU member states Irish holidaymakers may travel to in the coming weeks, and thereby avoid the requirement of a two-week quarantine when they return home.
Instead, it is expected ministers will discuss the criteria which will apply in deciding these so-called "air-bridges"; and what health considerations need to be taken into account with such travel.
