"These polls illustrate yet again the absolute necessity now for us to have a debate to begin preparations for a transition to a border poll and then beyond that to a united Ireland.

"The Government, and the Taoiseach in particular, needs to lead on that, there is no point burying their heads in the sand," she added.
