Yesterday, I read a document which has been circulated to the emergency services in the Irish Republic. This gives more detail than the announcement by Varadkar on May 1. In it, wrt sport - the obvious caveats applying, it says that golf could resume from May 18, subject to social distancing being observed. In a later phase, GAA and soccer - behind closed doors, would resume from July 20.
It will be interesting to see what Boris has to say on Sunday.
