Dublin's Lord Mayor, Mr Michael Conaghan, will lead a protest tomorrow against overcrowding at Dublin's Mater Hospital.
The demonstration is in response to the Government's failure to take action to end the crisis in the hospital's accident and emergency department.
The protest is organised by the Labour Party members and its supporters. Local TD and party justice spokesman Joe Costello said: "The presence of the Lord Mayor is a significant endorsement of these protests.
"The Mater has suffered serious cutbacks that have resulted in ward closures and cuts in vital treatments and services to patients.
"It is ridiculous that such a situation should exist in the heart of the Taoiseach's own constituency."
Mr Costello said the Labour Party in Dublin Central would continue to pressurise the Taoiseach and the Tanaiste "to stop all the waffle about health service improvements and to deliver on beds, nurses and A&E services at the Mater Hospital".
