An Irish department store has unveiled a chocolate bar to commemorate the 1916 Easter Rising.

The bar, which bears images of the seven executed rebel leaders and the proclamation on its wrapper, is being sold in Heatons stores in the Republic for €3.

Twitter user Justin Hourigan shared a picture of the display in the Tralee branch, which was mocked as the "choclamation".

But while some people said it could help make Irish history accessible to children, others believe it is disrespectful and fear the centenary commemorations next year will become "overly commercialised".

James Connolly Heron, great-grandson of 1916 leader James Connolly, said: "There's so much more we can tell about the 1916 leaders than reducing them down to covering a chocolate bar."

He told RTE's Liveline it was important to educate younger generations about the Rising, but said the bar was "simply a commercial venture".

"One would expect a certain amount of sensitivity particularly around those that were executed," he said.

I like Malcolm Byrne but totally disagree with him regarding 1916 chocolate, any measure that makes it more inclusive is welcome #liveline — Ken Curtin (@kencurtin) November 3, 2015

Fianna Fáil Wexford councillor Malcolm Byrne, who initially raised concerns about the bar, said the centenary must not be "overly commercialised".

Heatons has not responded to a request for a comment.
