Irish Taoiseach Seán Lemass met Northern Ireland premier Captain Terence O'Neill at Stormont on 14 January 1965.
It was the first official leaders' meeting in 40 years. O'Neill had approached Lemass through T. K. Whitaker, Secretary of the Department of Finance, and invited the Taoiseach to Northern Ireland.
R.J. Dowling reports for RTÉ News on the meeting, which he describes as "one of the most significant events in modern Irish history".
