The fourth major national day of protest against Irish Water and water charges will kick off later on this afternoon.
Road closures and traffic gridlock is expected around Dublin city centre.
There are three main meeting points: Merrion Square, Connolly Station, and Heuston Station. All groups will then converge on O’Connell Square, where a stage will be erected at the Parnell Square end.
A large turnout is expected, and the main protest is scheduled to finish at around 3pm. Smaller, regional protests will also take place today.
