A former Taoiseach says Arlene Foster's decision to resign as leader of the DUP and First Minister was an 'inevitable consequence' of Brexit.
John Bruton says many in the unionist community failed to fully consider its potential impact.
Foster will leave her role as First Minister at the end of June - and as leader of the DUP on the 28th of May - following a revolt within her party.
John Bruton says Brexit played a key role in her departure.
"Her resignation is an inevitable consequence of a lack of serious thought by the Unionist community as a whole about Brexit.
"Unfortunately a majority of unionists supported Brexit, even though the majority of Northern Ireland went the other way, and that was a mistake."
