Demonstrators gather at the GPO to protest at the visit of British Prime Minister Edward Heath.
British Prime Minister Edward Heath meets An Taoiseach Liam Cosgrave at Baldonnel Aerodrome for a summit aimed at negotiating a new plan for Northern Ireland and Anglo-Irish relations. The visit to Ireland is historic as it is the first by a serving British Prime Minister since independence.
In protest of the Heath visit, Sinn Féin (Gardiner Place) mount a major demonstration outside the General Post Office (GPO) on O'Connell Street. Placard carrying demonstrators chant anti-Heath slogans while they march to the GPO.
About 40 Córas Iompair Éireann (CIÉ) workers in Dublin also protest over the Edward Heath visit. They are supported by members of Sinn Féin (Kevin Street), the Irish Civil Rights Association and the Young Socialists.
A wreath is laid at Sackville Place in memory of three colleagues, bus drivers Thomas Duffy and George Bradshaw, who were killed in a car bomb blast on 1 December 1972 and bus conductor Thomas Douglas, another victim of a car bomb blast on 20 January 1973.
Hundreds of passers-by crowd around the demonstrators and An Garda Síochána have to divert traffic.
