Prime Minister Theresa May will host leaders of Northern Irish parties including Sinn Fein for talks in Downing Street tomorrow, as she continues to seek an informal alliance with unionists.
Leaders of the five main parties in the province have been invited, with May hoping to focus on restoring devolved government to the region.
Sinn Fein's Northern Irish Assembly leader Michelle O’Neill will be among the guests, and issued a statement flagging her concerns with May over a "confidence and supply" deal with the Democratic Unionist Party.
O'Neill said she would meet both May and new Irish Taoiseach Leo Varadkar in the coming days.
May hosted DUP officials for talks yesterday on an informal alliance yesterday. A spokeswoman for the DUP said they hope talks will be "coming to a conclusion soon", but the negotiations have raised eyebrows with former Prime Minister John Major questioning the impact on the Northern Irish peace process.
“I will be making it very clear that any deal between the Tories and the DUP cannot be allowed to undermine the Good Friday and subsequent agreements," O'Neill said.
"It's imperative that both governments recommit to the word, spirit and implementation of the Good Friday Agreement if there is to be any prospect of re-establishing the Executive [in Northern Ireland]."
Sinn Fein and the DUP dominate Northern Irish politics, with the two parties winning seven and 10 seats, respectively, from a total of 18 in the province.
However, Sinn Fein MPs have never taken their seats in Westminster.
