Sinn Fein says will oppose any deal that undermines peace deal

However, in January, Sinn Fein pulled out of the government over a corruption scandal involving DUP leader Arlene Foster, who is now negotiating with May.

"It takes two to tango and we're ready to dance", she said.

That agreement assigns the British government the role of broker between Irish republicans and unionists, a role that Mr Adams said would be compromised if the government was in some way indebted politically to the DUP.

This thinking reached its nadir at the St Andrews' Agreement, when a sectarian headcount at election time was entrenched in our devolved institutions.

May's government has said its Brexit plans remain the same, and will be pressing for close economic ties but a clear break with the bloc to be able to control immigration and restore sovereignty over British laws.

Through the 1970s-1990s, the DUP opposed successive accords that proposed Dublin's involvement in power-sharing arrangements, including the Good Friday Agreement, which ended decades of conflict and has maintained peace across Ireland.

"However, while talks are ongoing it is important the Government gets on with its business and we are confident there will be sufficient support across the House for passing the Queen's Speech".

"I think it is all very doable".

Michelle O'Neill, Sinn Féin's leader in the North, said: "We were very clear with the Prime Minister that any deal with herself and the DUP can not undermine the Good Friday Agreement".

"I am concerned about the deal, I am wary about it, I am dubious about it, both for peace process reasons but also for other reasons as well", he told BBC Radio 4's the World at One.

Asked about the political rollercoaster which has seen her removed from office as first minister then become the Kingmaker at Westminster, Mrs Foster said she had been kept going by the support of ordinary people.

However, she said her party would go back and look at an expert report on the issue of fatal foetal abnormality which is understood to recommend legal changes.

On Brexit, Ms Foster said her party wanted to see "a sensible Brexit and one that works for everybody".

"It's going to be hard, there's no doubt about that, but perhaps an opportunity to consult more widely with the other parties on how best we can achieve it", he said at a conference in Poland, the Financial Times reported.
