Enda Kenny, the Irish Prime Minister, has warned Theresa May that her pact with the DUP could put the peace process in Northern Ireland at risk as questions were raised about the Government’s ability to remain an impartial “honest broker”.

Mr Kenny, who will retire as Taoiseach later this month, spoke to Mrs May to voice his concerns over the “confidence and supply” arrangement that leaves the Tories relying entirely on the support of the unionist party’s 10 MPs to be able to govern.

James Brokenshire, the Northern Ireland Secretary, is due to resume talks on Monday to broker a deal between Sinn Fein and the Democratic Unionist Party to restart power-sharing in the Northern Ireland Assembly at Stormont.

The Assembly was suspended in March after the unionist parties lost their majority in Stormont and the two sides failed to agree on a new power-sharing deal.

Britain and Ireland act as co-guarantors of the Good Friday Agreement, the treaty that restored power to Stormont and ended the decades-long Troubles in the province.

Mr Kenny tweeted: “Spoke w PM May - indicated my concern that nothing should happen to put GoodFridayAgrmt at risk & absence of nationalist voice in Westminster.”

The Irish Foreign Minister Charlie Flanagan said he had raised the issue of the Government’s objectivity in a phone call with Mr Brokenshire.
