 During the 1964 UK general election campaign, an Irish republican candidate displayed an Irish tricolour from the window of his office in a republican area of Belfast.Paisley threatened that if the Royal Ulster Constabulary (RUC) did not remove the tricolour he would lead a march to the office and take it down himself.The Flags and Emblems Act banned the public display of any symbol, with the exception of the Union Flag, that could cause a breach of the peace.
