The First Minister of Northern Ireland Arlene Foster insists she was not attending a 1916 Easter Rising commemoration in Dublin last night.
She took part in a Church of Ireland talk about the rebellion against British rule at Christ Church Cathedral.
Organisers had billed it as a commemoration, but later issued a statement calling it a 'discussion'.
The Church of Ireland say the word 'commemorate' was "inadvertently used" in an earlier press release.
"The event is not a commemorative one but one which is designed to mark the centenary of the Easter Rising by exploring it historically", it added.
Ms Foster, the Democratic Unionist Party leader, says she has "a very particular view" on what happened 100 years ago.
