Conservative ministers would be "duplicitous" if they refused to give Scotland power over corporation tax at the same time as Northern Ireland, the SNP have claimed.
The Scottish nationalists have said it would be reprehensible if Westminster gives Northern Ireland "transformative" new powers to cut corporation tax but denies them to Scotland.
Redrawing Northern Ireland's border would be a "fatal mistake", ex-Irish premier Garret FitzGerald privately warned Margaret Thatcher, secret files have revealed.
THE last-minute deal that saved Northern Ireland's power-sharing executive from collapsing into bitter acrimony has been hailed as a "monumental step forward" that will help secure the UK region's long-term future.
A political agreement on a range of disputes that had undermined power-sharing in Northern Ireland has left the region facing a brighter and more prosperous future, the Prime Minister has said.
