Irish premier Enda Kenny expressed concern Sunday that a proposed alliance between Britain's ruling Conservatives and Northern Ireland's Democratic Unionist Party (DUP) could pose a challenge to the peace process for the province.

In a phone call with Prime Minister Theresa May, "the taoiseach indicated his concern that nothing should happen to put the Good Friday Agreement at risk and the challenge that this agreement (with the DUP) will bring", a spokesman said.
